SUMMARY:Graduate Student Colloquium: Eric Redmon
DESCRIPTION:Finite State Machines and Bounded Permutations\nEric Redmon\nGraduate Student\nMarquette University \nWe define a k-bounded permutation π of length n to be a permutation such that for each pair of adjacent entries $\pi$ and $\pi(i + 1)$ for $i = 1\, 2\, 3\, . . . \, n − 1$ we have $|\pi(i) − \pi(i + 1)| \leq k$. Previous work has shown that the generating function for this family of permutations is rational\, and has computed generating functions for small values of $k$. In this talk\, we will discuss the nature of finite state machines and how we can leverage the insertion encoding devised by Albert\, Linton\, and Ruškuc to build a finite state machine that we can use to find generating functions for larger values of $k$.

SUMMARY:Colloquium: Dr. Lei Hua
DESCRIPTION:Unified Tail Dependence Measures and Its Applications in High-Frequency Financial Data\nDr. Lei Hua\nAssociate Professor\, Director of Statistical Consulting Service\nNorthern Illinois University \nIn this presentation\, I will first motivate the necessity for a unified tail dependence measure\, followed by an examination of the theoretical framework for developing such measures utilizing random variables characterized by regularly varying tails. Specific instances that result in unified tail dependence measures applicable in practical scenarios will be demonstrated. Ultimately\, I will explore the application of the unified tail dependence measure in the analysis of high-frequency financial market data and discuss novel empirical insights from financial markets.

SUMMARY:Colloquium: Nick Mayers
DESCRIPTION:  \nWell-Behaved Kohnert Posets\nDr. Nicholas Mayers\nPostdoctoral Research Scholar\nNorth Carolina State University \nKohnert polynomials form a family of polynomials indexed by diagrams that consist of unit cells arranged in the first quadrant. Many families of well-known polynomials have been shown to be examples of Kohnert polynomials\, including key\, Schur\, and Schubert polynomials. Given a diagram D\, the monomials occurring in the corresponding Kohnert polynomial encode diagrams formed from D by applying sequences of certain moves\, called “Kohnert moves\,” each of which alters the position of at most one cell. In this talk\, we focus on the underlying sets of diagrams which generate the monomials of Kohnert polynomials. With each such collection of diagrams\, one can associate a poset structure which is known to not\, in general\, be well-behaved. In particular\, the corresponding “Kohnert posets” generally do not have a unique minimal element\, are not ranked\, and are not lattices. Here\, we will focus on recent attempts to find conditions under which Kohnert posets are well-behaved in the sense that they have a unique minimal element\, are ranked\, or are EL-Shellable. No background knowledge concerning posets is assumed.

SUMMARY:Colloquium: Dr. Sarah Sword
DESCRIPTION:Studying Successful Doctoral Students from Underrepresented Groups\nDr. Sarah Sword\nPrincipal Research Scientist\nEducation Development Center\, Inc. \nIn this talk\, we will share early findings from an NSF study of 75 doctoral students and recent PhDs in mathematics from underrepresented groups. The project has conducted in-depth\, semi-structured interviews with four cohorts: newly accepted students\, early graduate students (pre-qualifying exams)\, advanced graduate students (dissertation level)\, and recent PhDs (0-5 years since graduation). The research questions in the study are: (1) What are lived experiences of successful underrepresented students who are pursuing mathematics PhDs? and (2) What formal and informal structures are perceived by doctoral students as effective supports? Themes drawn from the interviews can inform department policies and practices to create environments that support students from underrepresented groups as they earn PhDs in mathematics.

SUMMARY:Colloquium: Ning Wei
DESCRIPTION:The Impact of Ephaptic Coupling and Ionic Electrodiffusion on Arrhythmogenesis in the Heart\nNing Wei\nAssistant Professor\nPurdue University \nCardiac myocytes synchronize through electrical signaling to contract heart muscles\, facilitated by gap junctions (GJs) in the intercalated disc (ID). GJs provide low-resistance pathways for electrical impulse propagation between myocytes\, serving as the primary mechanism for electrical communication in the heart. However\, research indicates that conduction can persist without GJs. For instance\, GJ knockout mice still exhibit slow\, discontinuous electrical propagation\, suggesting alternative communication mechanisms. Ephaptic coupling (EpC) serves as an alternative way for cell communication\, relying on electrical fields within narrow clefts between neighboring myocytes. Studies show that EpC can enhance conduction velocity (CV) and reduce conduction block (CB)\, especially when GJs are compromised.  Reduced GJs and significant electrochemical gradients are prevalent in various heart diseases. However\, existing models often fail to capture their combined influence on cardiac conduction\, which limits our understanding of both the physiological and pathological aspects of the heart.  Our study aims to address this gap by developing a two-dimensional (2D) multidomain electrodiffusion model that incorporates EpC. This is the first model to capture the dynamics of all ions across multiple domains\, enabling us to reveal the impact of EpC in the heart. In particular\, we investigated the interplay between ionic electrodiffusion and EpC on action potential propagation\, morphology\, electrochemical properties and arrhythmogenesis in both healthy and ischemic hearts. Our findings indicate that ionic electrodiffusion enhances CV and reduces CB under strong EpC. Specifically\, the electrodiffusion of Ca2+ and K+ intensifies the effects of EpC on action potential morphology\, whereas Na+ diffusion mitigates these effects. Ionic electrodiffusion also facilitates action potential propagation into ischemic regions when EpC is substantial. Moreover\, strong EpC can effectively terminate reentry\, prevent its initiation\, and lower the maximum dominant frequency (max DF)\, irrespective of GJ functionality. However\, weak EpC may help counteract proarrhythmic effects when GJ coupling is slightly to moderately reduced\, contributing to the stabilization of conduction patterns.  Additionally\, strong EpC  notably alters ionic concentrations in the cleft\, significantly increasing [K+] and nearly depleting [Ca2+]\, while causing moderate changes in [Na+]. This multidomain electrodiffusion model sheds light on the mechanisms of EpC in the heart.

SUMMARY:Colloquium: Dr. Alexander Wilson
DESCRIPTION:Symmetries and Diagram Algebras\nDr. Alexander Wilson\nVisiting Assistant Professor of Mathematics\nOberlin College \nIn this talk I will introduce you to the world of symmetric group representations through diagram algebras\, which trace their origin to the Temperley-Lieb algebra with applications in integrable models\, knot theory\, and quantum groups. For representation theory\, these algebras offer a sneaky path toward solving difficult problems by understanding the ways that graph-theoretic diagrams combine. The only background I will assume is some familiarity with linear algebra\, so if you like (or at least tolerate) playing around with pretty combinatorial objects\, I hope you’ll attend!

SUMMARY:Colloquium: Mr. Mike Clutterbuck
DESCRIPTION:Embeddings: The Language of AI\nMr. Mike Clutterbuck\nLead Data Scientist\nWantable Inc. \nEmbeddings are a core concept in machine learning that help AI understand and organize complex data. They take things like words\, images\, or user behavior and turn them into compact numerical representations\, making it easier for AI to spot patterns and relationships. This is how LLMs understand language and recommendation systems personalize content. \nMathematically\, embeddings work by placing similar items closer together in a structured space\, using techniques like matrix factorization\, neural networks\, and dimensionality reduction. This makes them essential for search\, personalization\, fraud detection\, next-word prediction\, and more. While they might seem abstract\, embeddings are working behind the scenes in many of the AI-powered products and tools we use today

SUMMARY:PhD Dissertation Defense: Kimberly Harry
DESCRIPTION:Kostant’s Formula and Parking Functions: Combinatorial Explorations\nKimberly Harry\nUniversity of Wisconsin-Milwaukee \nWe let L(λ) denote the irreducible highest weight representation of the classical simple Lie algebra g with highest weight λ. Kostant’s weight multiplicity formula gives a way to compute the multiplicity of a weight µ in L(λ)\, denoted m(λ\, µ)\, via an alternating sum over the Weyl group whose terms involve the Kostant partition function. The Weyl alternation set A(λ\, µ) is the set of Weyl group elements that contribute nontrivially to the multiplicity m(λ\, µ). We prove that Weyl alternation sets are order ideals in the weak Bruhat order of the Weyl group. Specializing to the Lie algebra of type A\, we prove that the Weyl alternation sets A(˜α\, µ)\, where ˜α is the highest root of sl_{r+1}(C) and µ is a positive root is a product of Fibonacci numbers. Using this result\, we show that the q-multiplicity of the positive root in the representation L(˜α) is precisely a power of q. We give a complete characterization of the Weyl alternation sets A(˜α\, µ)\, where µ is now a negative root of sl_{r+1}(C). We also show that the cardinality of these Weyl alternation sets satisfies a two-term recurrence relation involving Fibonacci numbers. Time permitting I will present further results related to collaborative projects I have contributed to during my years at UWM. \nAdvisor: Pamela E. Harris \nCommittee Members:\nProfs.

SUMMARY:Graduate Student Colloquium: Matt McClinton
DESCRIPTION:Fractal Geometry and Non-Integer Dimensions\nMatt McClinton\nPhD Graduate Student\nUniversity of Wisconsin-Milwaukee \nPopularized in the 1980s\, fractals have become something of a household name. These fractal sets often demonstrate peculiar topological properties. One such property is the notion of a fractal dimension. Sets such as the Cantor set\, Sierpinski Gasket (SG)\, and the von Koch curve are traditionally visualized in 2D images. However\, these sets actually exist in-between dimensions 1 and 2! \nCertain fractals can be built using what is known as an Iterated Function System (IFS)\, and there is a powerful theorem stating that having an IFS representation of a fractal provides a simple means of determining the fractal dimension. I will begin by stating the IFS that generates the Sierpinski Gasket. There are two transformations on the Gasket to which creates the Level-n Stretched Sierpinski Gasket (SSG^n). I will demonstrate how one constructs the IFS for SSG^n\, as well as provide the highlights to a theorem in which I prove the fractal dimension of SSG^n.

SUMMARY:Colloquium: Prof. Alastair Fletcher
DESCRIPTION:Infinitesimal Spaces of Quasiregular Mappings\nProf. Alastair Fletcher\nProfessor of Mathematical Sciences and Director of Undergraduate Studies\nNorthern Illinois University \nHow can we differentiate functions which are not differentiable? In the context of quasiregular mappings\, a generalization of holomorphic functions where now infinitesimal circles are mapped to infinitesimal ellipses\, there is a satisfactory answer to this question given by infinitesimal spaces. In this talk\, we will survey these objects and discuss some ongoing work with relevance to the Decomposition Problem for bi-Lipschitz maps.

SUMMARY:Colloquium: Dr. Jason DeBlois
DESCRIPTION:Some Things We Do and Don’t Know About Knots\nDr. Jason DeBlois\nAssociate Professor\nUniversity of Pittsburgh \nIn this talk\, “knot” will mean a circle embedded in three-dimensional space. These have been formally studied since the late 19th century. More recently\, new computational and geometric tools have allowed us to make substantial progress on understanding the landscape of knots and their invariants\, but they have also raised new questions. I will introduce the study of knots\, sketch its history\, and describe what is known (to me) about some of these questions relating to hyperbolic geometry.

SUMMARY:Graduate Student Colloquium: Ariel Minakawa and Gavin Sayrs
DESCRIPTION:Stirling Permutations to Increasing Plane Trees and Back\nAriel Minakawa and Gavin Sayrs\nUndergraduate Students\nUniversity of Wisconsin-Milwaukee \nA Stirling permutation is a permutation on the multiset {1\,1\, 2\, 2\, 3\, 3\, … \,n\, n} such that any numbers appearing between repeated values of i must be greater than i. Recall that a plane tree is a tree drawn on a plane with no edges crossing. An increasing plane tree is a plane tree where each vertex is labeled from 1 to n\, with labels increasing away from the root. Our main result establishes a bijection from Stirling permutations to its respective increasing plain tree.

SUMMARY:Colloquium: Prof. Shamgar Gurevich
DESCRIPTION:How you think on a function defined on 0\,1\,…\,N-1?\nProf. Shamgar Gurevich\nProfessor of Mathematics\nUniversity of Wisconsin-Madison \nBetween thousand to million times per day\, your cellphone calculates the Fourier Transform (FT) of certain functions defined on 0\,1\,…\,N-1\, with N large (order of magnitude of thousands and more). The calculation is done using the Fast Fourier Transform (FFT) – discovered by Cooley–Tukey in 1965 and by Gauss in 1805. \nIn the lecture I want to advertise a beautiful way—due to Auslander-Tolimieri—to obtain the FFT as a natural consequence of an answer to the following: \nQUESTION: How to think on the space of functions on the set 0\,1\,…\,N-1? \nEngineers tell us that there are two answers for this question: \n(A) as functions on that set\, where 0\,1\,…\,N-1 regarded as times; \nand\, \n(B) as functions on that set\, where 0\,1\,…\,N-1 regarded frequencies; \nand then the FT is an operator translating between the two spaces. \nIn the lecture\, I will explain that there is another answer\, i.e.\, a not so well-known third space (C)\, of arithmetic nature\, that also gives an answer to the above question\, and then the FFT appears simply as the composition of two operators:\nthe one translating between spaces (A) and (C)\, and the one that translates (C) to (B). \nRemark: The lecture is prepared to be understood to anyone who is familiar with basic linear algebra. In particular\, advanced undergraduate students\, from computer science\, engineering\, mathematics\, physics\, etc\, are more than welcome to attend.

SUMMARY:Graduate Student Colloquium: Jackson Thurmond
DESCRIPTION:Generalized Linear Model Approach to the Prediction of the Outcome of Mixed Martial Arts Fights\nJackson Thurmond\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nMixed martial arts is a complex combat sport that encompasses striking\, grappling and submissions. In a sport where fights can be won by finishing a fight or go to decision there is a multitude of factors that can influence the outcome of a fight. In the Ultimate Fighting Championship a fighter is either designated the red or blue corner. Since mixed martial arts is a sport in which two competitors fight\, and one is declared a winner\, the result of a fight can be thought of a binary classification problem. In an effort to determine which factors are statistically significant to a fight\, a generalized linear model approach was selected.

SUMMARY:Colloquium: Dr. Lauren Rose
DESCRIPTION:Quads\, Finite Geometry\, and Sidon Sets\nDr. Lauren Rose\nAssociate Professor of Mathematics\nBard College \nQuads is a SET-like card game\, produced by the AWM under the name “EvenQuads”. The cards can be represented as points in $\mathbb{Z}_2^6$​\, where a quad in the game corresponds to an affine plane in the finite geometry$ AG(6\,2)$. Our primary focus is on quad-free collections of cards\, which correspond to Sidon sets. We explore an Quads analog of the “Cap Set” problem for SET\, presenting results and ongoing research.

SUMMARY:Math Community of Practice: Let's Talk About Math Anxiety
DESCRIPTION:Math Community of Practice: Let’s Talk About Math Anxiety\n\nAccording to a March 2024 US News survey\, most college students report struggling with mental health issues. Given that mathematicians are typically not mental health professionals\, knowing how to address this in the classroom often falls outside the scope of our expertise. This session will introduce participants to the concept of math anxiety\, a mental health issue that affects how students perform in our classrooms. Participants will learn about the condition\, dispel some common myths and rumors about mental health in the classroom\, and leave with a list of research-supported interventions they can try in their classes to support students with math anxiety without sacrificing content or rigor. \nFacilitated by Beccah MacKinnon

SUMMARY:Colloquium: Dr. Suzanne Boyd
DESCRIPTION:Polynomial-time Computability of the Julia Set for Polynomial Skew Products of Two Complex Variables\nDr. Suzanne Boyd\nAssociate Professor\nUniversity of Wisconsin-Milwaukee \nIngrained in the modern study of dynamical systems is the use of computer experiments for revelation and illustration. In this talk\, I will explain a polynomial-time computer algorithm for approximating the Julia set of a polynomial skew product of two complex variables. I will begin by defining the involved terms\, including computability\, Julia set\, and polynomial skew product. This work is joint with Christian Wolf. It relies on some my previous work on designing and implementing rigorous computer algorithms to confirm results of the experimental observations on the dynamics of polynomial maps of two complex variables\, including polynomial skew products. These algorithms are designed to locate a neighborhood of the chain recurrent set\, build a model of the dynamics of the map on this set\, and attempt to determine hyperbolicity (or Axiom A) of the map on its chain recurrent set.

SUMMARY:Marden Lecture: Dr. Trachette Jackson
DESCRIPTION:Mobilizing Mathematics for the Fight Against Cancer\nDr. Trachette Jackson\nProfessor of Mathematics and Associate Vice President for Research – Strategic Partnerships and Inclusive Excellence\nUniversity of Michigan \nIt is an exciting time to work in the interdisciplinary field of Mathematical Oncology. Even TIME Magazine agrees\, “A team-based\, cross-disciplinary approach to cancer research is upending tradition and delivering results faster.” Mathematical oncologists apply mathematical and computational modeling approaches to every aspect of cancer biology\, from tumor initiation to malignant spread to treatment response. This talk will highlight a suite of mathematical models from the past and present designed to improve the efficacy of drug treatment strategies for cancer. Combined with existing and newly generated experimental data\, these mathematical models are poised to enhance the ability to combine promising drugs for clinical trials. This type of interdisciplinary science can reduce the time and costs associated with transitioning novel therapeutics approaches from “equations to bench to bedside.” \nReception to follow in LEC

SUMMARY:Marden Colloquium: Dr. Trachette Jackson
DESCRIPTION:Agent-based Modeling of Dysregulated Cell Signaling and the Tumor-Immune Landscape Predicts New Possibilities for Combination Therapy\nDr. Trachette Jackson\nProfessor of Mathematics and Associate Vice President for Research – Strategic Partnerships and Inclusive Excellence\nUniversity of Michigan \nMathematical models\, specifically agent-based models (ABMs)\, have shown recent successes in uncovering the multiscale dynamics that shape the trajectory of cancer. They have enabled the optimization of treatment methods and the identification of novel therapeutic strategies. To assess the combined effects on tumor growth and the immune response of monoclonal antibodies that boost the immune system (immunotherapy) and small molecule inhibitors (SMI) that counteract the effect of driver mutations\, we build and analyze an ABM that captures key facets of tumor heterogeneity and immune cell dynamics\, their spatial interactions\, and their response to therapeutic pressures. Our model predicts that under certain conditions\, immunotherapy alone is optimal; in others\, immunotherapy followed by mutation-targeted therapy is best. These results suggest that optimal treatment depends on the strength of cellular signaling pathways and highlight the need to quantify mutation-dependent cell signaling and the fitness advantage conferred on cancer cells harboring these mutations.

SUMMARY:Graduate Student Colloquium: Noah Mitchell\, Levi Montee\, and Harrison Piehowski
DESCRIPTION:The RSA Algorithm: Demonstration and Proofs\nNoah Mitchell\, Levi Montee\, and Harrison Piehowski\nGraduate Students\nUniversity of Wisconsin-Milwaukee \nIn this talk\, we will explore the RSA algorithm\, one of the most widely used cryptographic systems. Starting with a brief history of its development by Ron Rivest\, Adi Shamir\, and Leonard Adleman in the late 1970s\, we will then demonstrate RSA’s effectiveness through practical examples and mathematical proofs. Our presentation will include an interactive role-play\, where two presenters use RSA to securely send messages\, while a third attempts to decrypt them without the private key\, showcasing RSA’s robustness in real-world scenarios.

SUMMARY:Graduate Student Colloquium: Levi Montee
DESCRIPTION:Partitioning the Natural Numbers with Fibonacci-like Sequences\nLevi Montee\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nFamously seen in the displacement of seeds in a sunflower\, the branching of tree limbs or enumerating results in a variety of combinatorics problems\, the Fibonacci sequence has become one of the most recognizable sequences in mathematics. Beginning f0 = 0\, f1 = 1\, and continuing fn+1 = fn + fn-1\, this simple recurrence relation has been well studied for centuries. In this talk\, we will investigate sequences determined by the same recurrence relation given alternative starting points. We attempt to classify these sequences\, see which familiar Fibonacci properties are kept intact\, and examine when two such sequences share terms. Ultimately\, we aim to find a set of disjoint Fibonacci-like sequences that partition the natural numbers\, and see how these might be useful in solving particular logic games/puzzles.
