SUMMARY:Graduate Student Colloquium: Kushlam Srivastava
DESCRIPTION:An Introduction to Boundaries of Groups\nA key idea in the field of geometric group theory is to study geometric and topological objects associated with groups. Boundaries of groups are examples of such objects. In this talk we will look at boundaries of (relatively) hyperbolic groups and see how their topology is directly related to algebraic properties of groups. This expository talk is meant to be an entry point for the audience to explore geometric group theory and no prior knowledge except basic topology is needed.

SUMMARY:Colloquium: Prof. Trevor Leslie
DESCRIPTION:Sticky Particle Solutions of the Euler Alignment system \nThis talk is about the Euler Alignment system from the field of collective behavior. After a primer on modeling considerations and the equations at issue\, we discuss the weak solution theory developed by Leslie and Tan via using a sticky particle discretization technique pioneered by Brenier and Grenier. The special structure of the equations allows us a detailed look into the time-asymptotic behavior of the system\, including the structure of so-called “flocking states”.
