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:MS Thesis Defense: Mr. Jackson Thurmond
DESCRIPTION:Generalized Linear Model approach to the Prediction of the outcome of Mixed Martial Arts Fights\nMr. Jackson 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 an effort to determine which factors are statistically significant to a fight a generalized linear model approach was selected. 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. \nAdvisor:\nDavid Spade \nCommittee Members:\nDavid Spade\, Chao Zhu\, and Lijing Sun

SUMMARY:Colloquium: Prof. Caroline Terry
DESCRIPTION:Measuring Combinatorial Complexity via Regularity Lemmas\nProf. Caroline Terry\nAssociate Professor\nUniversity of Illinois-Chicago \nMany tools have been developed in combinatorics to study global structure in finite graphs. One such tool is called Szemerédi’s regularity lemma\, which gives a structural decomposition for any large finite graph. Beginning with work of Alon-Fischer-Newman\, Lovász-Szegedy\, and Malliaris-Shelah\, it has been shown over the last 15 years that regularity lemmas can be used to detect structural dichotomies in graphs\, and that these dichotomies have deep connections to model theory. One striking example is a dichotomy in the size of regular partitions\, first observed by Alon-Fox-Zhao. Specifically\, if a hereditary graph property H has finite VC-dimension\, then results of Alon-Fischer-Newman and Lovász-Szegedy imply all graphs in H have regular partitions of size polynomial is 1/ε. On the other hand\, if H has infinite VC-dimension\, then results of Gowers and Fox-Lovász show there are graphs in H whose smallest 1/ε-regular partition has size at least an exponential tower of height polynomial in 1/ε. In this talk\, I present several analogous dichotomies in the setting of hereditary properties of 3-uniform hypergraphs.

SUMMARY:Colloquium: Prof. Yangjin Kim
DESCRIPTION:Cytokine Shield Formation in Tumor Growth by Blocking Chemotactic Migration of T Cells in Response to CXCL12 from Senescent Tumor Cells\nProf. Yangjin Kim\nProfessor\nBrown University \nCellular senescence can induce dual effects (promotion or inhibition) on cancer progression. While immune cells naturally respond and migrate toward various chemotactic sources from the tumor mass\, various factors including senescent tumor cells (STCs) in the tumor microenvironment (TME) may affect this chemotactic movement. In this work\, we investigate the mutual interactions between the tumor cells and the immune cells (T cells and macrophages) that either inhibit or facilitate tumor growth by developing a mathematical model that consists of taxis-reaction-diffusion equations and receptor kinetics for the key players in the interaction network. We first apply a mathematical model to a transwell Boyden chamber invasion assay used in the experiments to illustrate that STCs can play a pivotal role in negating immune attack through tight regulation of intra- and extra-cellular signaling molecules. The mathematical model consists of a system of parabolic-hyperbolic PDEs with two separate model domains based on experimental setting empirical data. Neuman B.C. on the outer boundary and Interface B.C. from homogenization of holes of various sizes on porous membrane are assigned. In particular\, we show that senescent tumor cells in cell cycle arrest can block intratumoral infiltration of CD8+ T cells by secreting a high level of CXCL12\, which leads to significant reduction its receptors\, CXCR4\, on T cells\, and thus impaired chemotaxis. Macrophages also play an important role in mediating or inhibiting given signaling pathways between different cells in TME. The predictions of nonlinear responses to CXCL12 were in good agreement with experimental data. We tested several hypotheses on immune-tumor interactions under various biophysical- and biochemical- conditions in the tumor microenvironment and developed new concepts for anti-tumor strategies targeting senescence induced immune impairment. \n

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

SUMMARY:Colloquium: Prof. Christian Wolf
DESCRIPTION:  \nMeasures of Maximal Entropy on Coded Shift Spaces: Uniqueness and Computability\nProf. Christian Wolf\nExecutive Officer and Professor\nCUNY Graduate Center and City College \nIn this talk\, we present results about the uniqueness and computability of measures of maximal entropy on coded shift spaces. A coded shift space is defined as the closure of all bi-infinite concatenations of words from a fixed countable generating set. We derive sufficient conditions for the uniqueness of measures of maximal entropy based on the partition of the coded shift into its concatenation set (sequences that are concatenations of generating words) and its residual set (sequences added under the closure). We also discuss flexibility results for the entropy on the concatenation and residual sets. Next\, we present a local structure theorem for intrinsically ergodic coded shift spaces\, which shows that our results apply to a larger class of coded shift spaces compared to previous works by Climenhaga\, Climenhaga and Thompson\, and Pavlov. Finally\, if time permits\, we discuss the computability (in the sense of computable analysis) of measures of maximal entropy for coded shift spaces. The results presented in this talk are joint work with Tamara Kucherenko and Martin Schmoll. \n  \n

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: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. 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. 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:Graduate Student Colloquium: Kimberly Hadaway
DESCRIPTION:Parking Completions and Volumes of Polytopes\nKimberly Hadaway\nGraduate Student\nIowa State University \nParking functions correspond with preferences of n cars which enter sequentially to park on a one-way street where (1) each car parks in the first available spot greater than or equal to its preference and (2) all cars successfully park. We generalize parking functions to parking completions: Here\, we are given that some cars have already parked in a set of spots\, which are indexed in a vector t. We then consider a preference vector c\, where len(t)+len(c)=n. If all cars can park\, we say that c is a parking completion. Adeniran\, et al. (2020) state an open problem which connects the number of parking completions to the volumes of Pitman-Stanley polytopes by explicit computation on small values of n. In this talk\, we provide a partial solution to this open problem by exploring edge cases.

SUMMARY:Colloquium: Dr. Dexuan Xie
DESCRIPTION:Recent Advances in Nonlocal Dielectric Continuum Models for Predicting Protein and Ion Channel Electrostatics\nDr. Dexuan Xie\nProfessor\nUniversity of Wisconsin-Milwaukee \nThe calculation of electrostatics for proteins and ion channels is a fundamental challenge in structural biology\, computational biochemistry\, biophysics\, and mathematical biology. Traditional dielectric continuum models\, such as the Poisson–Boltzmann equation and its variants\, are widely used for this calculation. However\, their prediction accuracy often deteriorates near highly charged biomolecular surfaces because they neglect the polarization correlations of water molecules. To address these limitations\, a nonlocal dielectric continuum modeling approach was introduced roughly four decades ago. Over the past decade\, this approach has seen substantial theoretical and computational advances\, largely driven by our group’s work under support from the National Science Foundation. \nIn this seminar\, I will present our nonlocal dielectric theory and report our recent progress in developing nonlocal dielectric continuum models and finite element solvers for proteins and ion channels. I will also compare the predictions of our novel nonlocal models with those of the traditional local models and present numerical results demonstrating the efficiency of our solvers and the high performance of our software package. This work is a collaboration with my students\, Liam Jemison and Matthew Stahl. It has been partially supported by the National Science Foundation under award DMS-2153376 and by the Simons Foundation under research award 711776.

SUMMARY:Graduate Student Colloquium: Jillian Cervantes
DESCRIPTION:The Axiom of Choice and Non-Lebesgue Measurable Sets\nJillian Cervantes\nGraduate Student\nUniversity of Wisconsin-Milwaukee \nIn this expository talk\, we explore an interesting connection between the axiom of choice and the existence of non-Lebesgue measurable subsets of \mathbb{R}. We state the axiom of choice and discuss its meaning and significance before reviewing properties of measures\, Lebesgue measure\, and Lebesgue measurable sets. The talk concludes with a construction which uses the axiom of choice to prove the existence of non-Lebesgue measurable sets.

SUMMARY:Colloquium: Prof. Greg Ongie
DESCRIPTION:A Function Space View of Neural Networks\nProf. Greg Ongie\nAssistant Professor\nMarquette University \nMany mathematical analyses of deep learning focus on how neural network (NN) parameters evolve during training. A complementary perspective is to view NN training as fitting a function belonging to a function space implicitly defined by the architecture and training procedure. In particular\, when parameter norms are explicitly or implicitly constrained\, NNs exhibit a bias toward functions with low “representation cost\,” defined as the minimal parameter norm required to realize the function with a given NN architecture. This talk surveys recent results that characterize representation cost of shallow NN architectures in terms of Banach space norms\, and through non-linear notions of function rank for deeper NN architectures. Finally\, we discuss how bias towards low representation cost functions helps to explain generalization in various applications.

SUMMARY:Colloquium: Dr. Daniel Noelck
DESCRIPTION:Exponential Stability Of The Discrete Stochastic Filter Via Non-degeneracy Andanalytic Stability Of The Signal\nDr. Daniel Noelck\nSenior Research Associate\nIllinois Institute of Technology \nThe stability of discrete time filters has been an active field of research\, particularly when applied to numerical filter approximation schemes. Most results in the field are obtained on a compact signal space\, but there is no reason to believe the results should not carry over to non-compact spaces. In this talk\, we will introduce the discrete time filtering problem\, discuss some well known results on compact spaces\, and the difficulties of expanding those results to non-compact spaces\, and then introduce recent results for stability on those non-compact spaces. Finally\, we will discuss the future work available in the continuous time setting.
