SUMMARY:PhD Dissertation Defense: Mr. Liam Jemison
DESCRIPTION:A Nonlocal Poisson–Boltzmann Model\, Finite Element Solver\, and Parallel Implementation for Ion Channels in Multispecies Ionic Solutions\nMr. Liam Jemison\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nWe introduce the first nonlocal Poisson–-Boltzmann Ion Channel (NPBIC) model and corresponding finite element solver for three-dimensional ion channel–membrane systems in solvents with multiple ionic species. Although the NPBIC model presents numerical challenges caused by strong nonlinearities\, nonlocal convolution terms\, discontinuous interface conditions\, and solution singularities induced by atomic point charges\, we develop a novel decomposition technique for solving the model. We present a parallel NPBIC finite element solver package\, and a host of numerical experiments and validation. \nAdvisor:\nDexuan Xie \nCommittee Members:\nIstvan Lauko\, Gabriella Pinter\, Lei Wang\, and Peter Hinow

SUMMARY:PhD Dissertation Defense: Mr. Andrew Frohmader
DESCRIPTION:Graded multiplicities in the Kostant-Rallis setting\nMr. Andrew Frohmader\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nThis dissertation contains two main results. First\, we provide combinatorial branching rules for GL(n\, C) to O(n\, C) and GL(2n\, C) to Sp(2n\, C) extending the Littlewood restriction rules. Second\, we use these branching rules and the combinatorics of GL(n\, C)-crystals to derive a formula for the graded multiplicity of a K-type in the regular functions on the K-nilpotent cone for GL(n\, R)\, GL(n\, C) and GL(n\, H). \nAdvisor:\nJeb Willenbring \nCommittee Members:\nAllen Bell\, Chris Hruska\, Istvan Lauko\, and Kevin McLeod

SUMMARY:UWM Marden Lecture in Mathematics: Juggling Counts
DESCRIPTION:Juggling Counts\nPresented by Prof. Steve Butler\, Morrill\, Professor of Mathematics at Iowa State University \nMathematics is a language which can help us describe and explore patterns. One source of patterns that mathematicians have been exploring comes from juggling (the tossing of objects\, usually balls or clubs). We will look at multiple ways to describe juggling patterns that allow us to find new juggling patterns\, and to count how many possible patterns exist. We can compare answers to various problems to give a combinatorial proof of Worpitzky’s identity. We will also look at a few juggling-based problems that mathematics has not yet succeeded in answering. \nThis event is a part of the Marden Lecture Series\, each Spring the Department of Mathematical Sciences invites a distinguished mathematician to lecture to a general audience. The Marden Lecture honors Morris Marden (1905 – 1991)\, who founded our graduate program and made our department a research department. The Marden lecture is funded through the Miriam and Morris Marden Fund and is co-sponsored by the Department of Mathematical Sciences. \nA banquet will be held in the LEC AmFam Dream Studio following the lecture.

SUMMARY:PhD Dissertation Defense: Mr. Marco Vaassen
DESCRIPTION:A Bootstrap Goodness-of-Fit Test for Parametric Survival Models\nMr. Marco Vaassen\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nIn many scientific disciplines\, finding a suitable model compatible with real-world observations is the basis for statistical inference and prediction. In survival analysis\, this task is further complicated by censoring. This dissertation introduces a new bootstrap approach to goodness-of-fit testing for parametric survival models\, based on the Kaplan–Meier process with estimated parameters. The test statistic compares the nonparametric Kaplan–Meier estimator to a fitted parametric model\, quantifying deviations from the null via functionals that yield Kolmogorov–Smirnov or Cramér–von Mises-type tests. We establish the asymptotic correctness of our method by showing that the original and bootstrap test statistics have the same weak limit under the null. The result is a consistent\, easily implementable framework for assessing model fit in censored settings. \nAdvisor:\nProf. Richard Stockbridge\, Prof. Gerhard Dikta \nCommittee Members:\nProf. Richard Stockbridge\, Prof. Gerhard Dikta\, Prof. Chao Zhu\, Prof. David Spade\, and Prof. Vincent Larson

SUMMARY:PhD Dissertation Defense: Mr. Shenyan Pan
DESCRIPTION:Doubly Stochastic Model With Covariates For Replicated Poisson Point Processes\nMr. Shenyan Pan\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nPoisson point processes (PPPs) are powerful tools for modeling random point occurrences in multidimensional spaces\, with applications across various fields. Although the traditional literature has focused on single realizations\, replicated point processes are becoming increasingly common due to the growing availability of complex data. This dissertation develops a doubly stochastic model for replicated PPPs that incorporates covariates\, extending latent component models to capture external effects. The proposed model expresses the log-intensity function as the sum of a mean function and latent component scores that vary with covariates. To ensure identifiability\, component scores are constrained to be zero-mean and uncorrelated via centering and orthogonality. Parameter estimation is performed using penalized maximum likelihood\, employing Newton–Raphson updates and the Laplace approximation for conditional distributions. Simulation studies assess the model’s stability across various covariate structures (linear and nonlinear)\, baseline rates\, and sample sizes. The results demonstrate decreasing error with increasing sample size\, confirming the estimators’ consistency. The model is applied to real data from the Divvy bicycle-sharing system in Chicago\, analyzing daily usage at a representative station. The results reveal a nonlinear relationship between temperature and ridership\, with peak usage occurring at moderate temperatures and declines observed under extreme heat or cold. This modeling framework improves the interpretability and predictive accuracy of PPPs with covariates\, offering practical insights for applications such as fleet allocation in bicycle-sharing systems. \nAdvisor:\nProf. Daniel Gervini \nCommittee Members:\nProf. Lei Wang\, Prof. Chao Zhu\, Prof. David Spade\, and Prof. Vytaras Brazauskas \nLink to Event

SUMMARY:PhD Dissertation Defense: Mr. Joe Paulson
DESCRIPTION:Theory of Z_n – Structures\nMr. Joe Paulson\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nIn this defense\, we discuss the boundaries of Type F_n groups; those being groups whose K(G\,1) complex has a finite n-skeleton. The boundaries we develop extend the notion of Z-boundaries to what we call Z_n-boundaries. This extension centers around groups no longer acting geometrically on contractible spaces\, but instead n-connected spaces. Immediately this means the major theorems of “Boundary Swapping” and “Shape Equivalence of Z-Boundaries” will need revision\, but a more subtle point to be discussed is that the category of spaces must also be generalized. \nAfter discussing the foundation work for a theory of Z_n-boundaries\, we end with an exploration how these new structures can be related to other well-known compactifications such as the one-point compactification\, end-point compactification\, and Z-compactifications. \nAdvisor:\nCraig Guilbault \nCommittee Members:\nBoris Okun\, Chris Hruska\, Jonah Gaster\, and Pamela Harris

SUMMARY:PhD Dissertation Defense: Mr. Steffen Domke
DESCRIPTION:Convergence Of A Numerical Scheme For Optimal Stopping Of A Diffusion Over A Finite Time-Horizon\nMr. Steffen Domke\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nThis dissertation establishes an approximation scheme for finite time-horizon\nstopping problems involving a singular stochastic process on a compact state\nspace\, characterized by a singular martingale problem. The stopping problem\nis converted to a linear program (LP) with infinitely many constraints and\nvariables having infinite degrees of freedom. \nTo obtain a numerical solution\, the infinite-dimensional LP is converted\ninto a finite LP. The original LP is approximated by a sequence of finite LPs\,\nlimiting to both a finite set of constraints and a finite-dimensional solution\nspace. The value of an optimal approximate solution is shown to be arbitrarily\nclose to the optimal value of original LP\, and hence of the stopping probem\,\nwith increasing refinement of the approximation. Feasibility of the approximate\nsolutions is guaranteed due weak convergence of measures\, but only in the limit.\nThe problem of pricing an American floating strike lookback call option can be\nreformulated to fit the models covered by this dissertation. The price and the\nstopping boundary can therefore be approximated using this scheme. \nAdvisor:\nRichard Stockbridge \nCommittee Members:\nDavid Spade\, Lei Wang\, Jeb Willenbring\, and Chao Zhu

SUMMARY:MS Thesis Defense: Mr. Micah Hesketh
DESCRIPTION:Compartmental Ordinary Differential Equation Model of the Amyloid-beta Cascade Hypothesis in Transgenic TgF-344AD Rats\nMr. Micah Hesketh\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nAlzheimer’s disease is a devastating neurodegenerative disease whose etiology is poorly understood and for which current treatments provide modest control of symptoms. There are many different hypotheses which seek to explain the cause of this disease\, one of which is the Amyloid-beta cascade hypothesis. To better investigate the causes and progression of the disease\, animal models have been developed\, notably the transgenic TgF344-AD rat. We combine observations on the accumulation of amyloid-beta\, changes in neuronal density\, and a decline in cognitive performance in rats with a simple compartmental ordinary differential equation model based on the Amyloid-beta cascade hypothesis. \nAdvisor:\nPeter Hinow \nCommittee Members:\nDr. Peter Hinow\, Dr. Gabriella Pinter\, and Dr. Lijing Sun

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 an effort to determine which factors are statistically significant to a fight a generalized linear model approach was selected.

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.

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.
