Title	The Wehrl entropy problem: mathematical physics meets complex analysis and representation theory
Speaker, Affiliation	Rupert Frank , Universität München

Location	KO2 F 150
Abstract	The coherent state transform, under various names, appears in many fields of mathematics and physics. It is associated with representations of a group. In this talk we are concerned with the problem of minimizing the entropy of the coherent state transform and we explain how complex analysis can be used to achieve this in certain settings. We discuss various open questions

Title	Computation in homotopy theory
Speaker, Affiliation	Dan Isaksen, Wayne State University
Date, Time	15 October 2024, 16:30-18:15
Location	KO2 F 150
Abstract	In part, the goal of homotopy theory is to compute algebraic invariants of topological objects. Of particular interest is the computation of homotopy groups of spheres. Any given result can typically be obtained in several completely distinct ways, using methods that have no visible consistency with each other. It is remarkable that there exists a solution to this highly overdetermined problem. Like many areas of pure mathematics, machine computation can be applied to great effect in this endeavor. I will discuss the history, current state of the art, and future prospects of machine computation in homotopy theory.
