David Gerard - Department of Statistics, University of Chicago
Feb 23, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Robert A. Pritzker Science Center, Room 152
Modern genomics has revolutionized how we answer questions about evolution, population dynamics, medicine, and plant and animal breeding. To answer these questions, we must first be able to detect and quantify (or "genotype") differences in individual genomes. Many scientists have used next... read more

Alexandr Kostochka - Department of Mathematics, University of Illinois at Urbana-Champaign
Mar 5, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
Dvořák and Postle introduced DP-coloring to answer a question of Borodin on list-coloring of planar graphs. Formally, a DP-\(k\)-coloring of a graph \(G\) is not exactly a coloring, but is an independent set in an auxiliary graph \(H(G,k)\). However, DP-coloring has many properties... read more

René Carmona - Department of Operations Research and Financial Engineering, Princeton University
Mar 26, 2018 - 6:00pm to 7:00pm
Department of Applied Mathematics - Lecture - Hermann Hall Ballroom
Motivated by a few concrete examples such as bird flocking, congestion for crowd motion, and bee swarming, we introduce the mean field game paradigm; and we present the underpinnings of the original analytic approach based on partial differential equations, and the probabilistic approach based on... read more

Andrei Tarfulea - Department of Mathematics, University of Chicago
Feb 13, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Robert A. Pritzker Science Center, Room 240
Understanding the behavior of solutions to physically motivated evolution equations is one of the most important areas of applied analysis. Developing strong bounds and asymptotics are crucial for anticipating the behavior of simulations, simplifying the methods needed to model the physical... read more

Sergey Nadtochiy - Department of Mathematics, University of Michigan
Feb 12, 2018 - 3:15pm to 4:15pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
In this talk, I will analyze a system of particles with singular interaction through hitting times. Such systems have been used in Neuroscience, but are also well suited for modeling Systemic Risk. I will discuss the latter application and will proceed to the analysis of a large-population limit of... read more

Vishesh Karwa - Department of Statistics & Department of Computer Science, Harvard University
Feb 12, 2018 - 1:50pm to 2:55pm
Department of Applied Mathematics - Colloquia - Rettaliata Engineering Center, Room 104
Stochastic Block models (SBM) with unknown block structure are widely used to detect community structure in real world networks.  SBM comes in many variants, hence it is essential to evaluate the fit of these variants. Testing the goodness-of-fit of such models is a challenging task due to the... read more
