This talk deals with quantifying the rate of contraction of the relative entropy with respect to a reference probability measure under the action of a Markov kernel. Sharp contraction estimates for Markov kernels are useful in a variety of settings, including distributed communication and simulation, exact and approximate stochastic filtering, a...

Binita Rai was born in a refugee camp in Nepal in 1997. Her parents were born in Bhutan but moved to Nepal because they were Nepali and could not stay during the civil war. In 2014, the family applied for resettlement in the United States. In September 2015, they resettled in Colorado. A year later they moved to Minnesota to join relatives alrea...

In this talk, we describe a range of tools available for modeling and solving mathematical optimization problems in Python. The tools range from high-level Python-based modeling languages to low-level solver APIs for passing optimization problem data directly to solvers. Examples and code snippets will be given to illustrate the use of these too...

We develop a general framework for the study of a class of randomized load balancing models in networks with many servers and in the presence of general service distributions. A key ingredient is a convenient Markovian representation of the state in terms of interacting measure-valued processes. We apply the framework to establish mean-field lim...

Finite-dimensional diffusions have been successfully used as tractable approximations to gaininsight into a large class of queueing systems. We show that certain classes of queueingsystems lead naturally to infinite-dimensional diffusion approximations. For the particular model of many-server queues, we show that the limit state processconverges...

Two approaches to characterizing reflected diffusions include the submartingale problem formulation or a formulation in terms of the Skorokhod problem and stochastic differential equations. We introduce these formulations for a large class of piecewise smooth domains and, under suitable assumptions, we show that well-posedness of the submartinga...

Reflected or constrained diffusions in convex polyhedral domains arise in a variety of disciplines, including as approximations of queueing and chemical reaction networks, interacting particle systems, Leontief systems in economics, and in the study of Atlas models in math finance. We establish pathwise differentiability of a large class of obli...
