SUMMARY:Graduate Student Colloquium: Jillian Cervantes
DESCRIPTION:(t\,r) Broadcast Domination of the Truncated Square Tiling Graph\nJillian Cervantes\nGraduate Student\nUniversity of Wisconsin – Milwaukee \nThis talk will introduce graph domination theory and a generalization called (t\,r) broadcast domination. We study a family of graphs that arise as a finite subgraph of the truncated square tiling\, which utilizes regular squares and octagons to tile the Euclidean plane. For positive integers m and n\, we let Hm\,n be the graph consisting of m rows of n octagons (cycle graph on 8 vertices). For all t ≥ 2\, we provide lower and upper bounds for the (t\, 1) broadcast domination number for Hm\,n for all m\, n ≥ 1. We give exact (2\, 1) broadcast domination numbers for Hm\,n when (m\, n) ∈ {(1\, 1)\, (1\, 2)\, (1\, 3)\, (1\, 4)\, (2\, 2)}. We also consider the infinite truncated square tiling\, and we provide constructions of infinite (t\, r) broadcasts for (t\, r) ∈ {(2\, 1)\, (2\, 2)\, (3\, 1)\, (3\, 2)\, (3\, 3)\, (4\, 1)}. Using these constructions we give upper bounds on the density of these broadcasts i.e.\, the proportion of vertices needed to (t\, r) broadcast dominate this infinite graph. We end with some directions for future study

SUMMARY:Colloquium: Dr. Zhaosheng Feng
DESCRIPTION:Parabolic System of Aggregation Formation in Bacterial Colonies\nDr. Zhaosheng Feng\nEndowed Chair Professor of Mathematics\nUniversity of Texas Rio Grande Valley \nThe goal of this talk is to study a fourth-order nonlinear parabolic system with dispersion for describing bacterial aggregation. Analytical solution of traveling wave is found by taking into account the dispersion coefficient. Numerically\, we demonstrate that the initial concentration of bacteria in the form of a random distribution over time transforms into a periodic wave\, followed by a transition to a stationary solitary wave without dispersion.

SUMMARY:Graduate Student Colloquium: Kelsey Brouwer
DESCRIPTION:Combinatorial Models for Some Generalized McMullen Maps in the Case of Two Bounded Critical Orbits\nKelsey Brouwer\nPhD Student\nUniversity of Wisconsin – Milwaukee \nThe family of generalized McMullen maps R(z)= z^n + b + a/z^n has two independent critical orbits. We consider the case in which one critical value lies in the immediate basin of an attracting cycle and the other critical value eventually lands in that immediate basin. Computer-generated images of the dynamical plane suggest the presence of both baby quadratic Julia sets and some sets which appear to be modifications of those. We present combinatorial models of the dynamics which help to explain this phenomena.

SUMMARY:Colloquium: Dr. Daniel Stoertz
DESCRIPTION:Baby Mandelbrot Sets for Maximally Generalized McMullen Maps\nDr. Daniel Stoertz\nVisiting Assistant Professor of Mathematics\nSt. Olaf College \nIn Complex Dynamics\, we study the iteration of holomorphic or meromorphic functions on the complex plane or the Riemann sphere. Of particular interest is the behavior of the critical orbits of function families with one or more parameters. The simplest of such families\, z^2 +c\, is well-known to define the famous Mandelbrot set fractal as the set of c-values for which the unique critical orbit is bounded. In this talk we will examine the function family R(z) = z^n +b +a/(z^d)\, and we will explore old and new results establishing the location of baby Mandelbrot sets in parameter space for increasingly general versions of this family. In the most general case\, which we call maximally generalized McMullen maps\, this family has multiple independent critical orbits\, and the dynamics in this case are not yet well understood.

SUMMARY:ICMA-IX
DESCRIPTION:  \n \nInternational Conference on Mathematical Modeling and Analysis of Populations in Biological Systems \nThe broad\, general theme of the conference is the formulation\, validation\, analysis and simulation of mathematical models for the spatiotemporal dynamics of biological populations. A special emphasis at this ninth conference will be placed on multiple scale dynamics in ecology\, epidemiology\, and systems biology; many biological systems operate on multiple spatial and temporal scales and the incorporation of these scales may be essential for capturing system dynamics. Specific topics include\, but are not limited to: \n\nImmuno-epidemiological and vector-host systems\nMolecular-cellular modeling in systems biology and oncology\nBiological invasions and persistence\nAdaption and evolutionary dynamics\nBiological systems operating on multiple spacial or temporal scales\n\nICMA-IX aims to accomplish at least three broad tasks: scientific progress\, scientific collaboration\, and the training of a future generation of mathematical biologists. The conference will thus have a significant impact\, both nationally and internationally\, on future research in biomathematics and mathematical biology. The collaborative opportunities provided to researchers at all points of the career path from undergraduate and graduate students\, to early-career faculty\, to established senior researchers will establish new directions and avenues for the national and international research community. \nHosts: \nPeter Hinow\nProfessor\nEMS\, E491\nhinow@uwm.edu \nGabriella Pinter\nProfessor\nEMS\, E479\ngapinter@uwm.edu

SUMMARY:Graduate Student Colloquium: Gregory Mwamba
DESCRIPTION:Blowup of the Nonlinear Klein-Gordon Equation in FLRW Spacetimes\nGregory Mwamba\nGraduate Student\nUniversity of California – Merced \nThe nonlinear Klein-Gordon equations are a class of important evolution equations that describe the movement of spinless relativistic particles\, which can lend understanding in many physical applications. In this talk we will demonstrate a sufficient condition for blowup of the nonlinear Klein-Gordon equation\, with arbitrarily positive initial energy in Friedmann-Lemaître-Robertson-Walker spacetimes. This is accomplished using an established concavity method that has been employed for similar PDEs in Minkowski space. This proof relies on the energy inequality associated with this equation. \nThis talk will be online at the following zoom link: https://wisconsin-edu.zoom.us/j/94983351854 and will also be streamed in EMS E495.

SUMMARY:Colloquium: Prof. Qingshuo Song
DESCRIPTION:Long-Time Behaviors of Stochastic Linear-Quadratic Optimal Control Problems\nProf. Qingshuo Song\nAssociate professor\nWorcester Polytechnic Institute \nIn this talk\, we will discuss the asymptotic behavior of the solution to a linear-quadratic stochastic optimal control problems. By establishing a connection between the ergodic cost problem and the so-called cell problem in the homogenization of Hamilton-Jacobi equations\, we reveal the turnpike properties of the linear-quadratic stochastic optimal control problems from various perspectives.
