Mathematical Biology seminar: Modeling and Global Sensitivity Analysis of Strategies to Mitigate Covid-19 Transmission on a Structured College Campus

Speaker: Dr. Lihong Zhao from University of California, Merced   Abstract: In response to the COVID-19 pandemic, many higher educational institutions moved their courses from face-to-face instruction to online or hybrid instruction, in hopes of slowing disease spread. The advent of multiple highly-effective vaccines offers the promise of a return to “normal” in-person operations, but … Continue reading Mathematical Biology seminar: Modeling and Global Sensitivity Analysis of Strategies to Mitigate Covid-19 Transmission on a Structured College Campus

PADS Seminar: Renewal Theory for Maxima on Trees

Speaker: Michael Conroy (University of Arizona) Abstract: This talk focuses on the all-time supremum W of the perturbed branching random walk, which is the so-called endogenous solution to the stochastic fixed-point equation known as the high-order Lindley equation. Under certain assumptions (in particular that the paths of each branch of the random walk have negative … Continue reading PADS Seminar: Renewal Theory for Maxima on Trees

Mathematical Biology seminar: “Careful or colorful? The evolution of animal ornaments”

Speaker: Professor Daniel Abrams from Engineering Sciences and Applied Mathematics, Northwestern University. Abstract: Extravagant and costly ornaments (e.g., deer antlers or peacock feathers) are found throughout the animal kingdom. Charles Darwin was the first to suggest that female courtship preferences drive ornament development through sexual selection. In this talk I will describe a minimal mathematical model for the … Continue reading Mathematical Biology seminar: “Careful or colorful? The evolution of animal ornaments”

PADS Seminar: Deep Learning for Data with Geometric Structure

Speaker: Michael Perlmutter (UCLA) Abstract: The field of Geometric Deep Learning aims to extend the success of Convolutional Neural Networks to data sets that lack a Euclidean, grid-like structure and are more naturally modeled as manifolds or (possibly directed). A major advance in this field has been the rise of graph convolutional networks which extend … Continue reading PADS Seminar: Deep Learning for Data with Geometric Structure

PADS Seminar: Convergence of Empirical Measures, Mean-Field Games and Signatures

Speaker: Ruimeng Hu (UC – Santa Barbara)   Abstract: In this talk, we first propose a new class of metrics and show that under such metrics, the convergence of empirical measures in high dimensions is free of the curse of dimensionality, in contrast to Wasserstein distance. Proposed metrics originate from the maximum mean discrepancy, which … Continue reading PADS Seminar: Convergence of Empirical Measures, Mean-Field Games and Signatures

Logic Seminar: Some fruit from set theoretic pluralism Part 2

Speaker: Henry Klatt (ISU)   Abstract: Unlike arithmetic, the identification of a canonical model of set theory is incredibly difficult. In this respect, the situation is more akin to geometry than arithmetic. We are capable of simulating alternative models with different structural properties within V, using either boolean valued forcing or a simulated ultrapower. This … Continue reading Logic Seminar: Some fruit from set theoretic pluralism Part 2

Math Biology Seminar: Insights into viral coinfections from mathematical models

Speaker: Hana Dobrovolny from Texas Christian University Abstract: Many patients hospitalized with influenza-like illnesses have been found to be infected with more than one virus. Clinical studies have found mixed results when investigating whether coinfections lead to more severe disease, with some studies even suggesting that coinfections are less severe than mono-infections. In vitro studies … Continue reading Math Biology Seminar: Insights into viral coinfections from mathematical models

PADS Seminar: Quasi-stationary distribution and ergodic control problems

Speaker: Guo-Jhen Wu (KTH Royal Institute of Technology) Abstract: We introduce two ergodic control problems that can be used to analyze the quasi-stationary distributions (QSDs) associated with a diffusion process. The two problems are in some sense dual, with one defined in terms of the generator associated with the diffusion process and the other in … Continue reading PADS Seminar: Quasi-stationary distribution and ergodic control problems
