Our first colloquium of the year will be given by Rupert Frank from LMU Munich on Thursday, 26th September, at 15:45 in Room Bush House (SE) 1.05. A reception will follow at 17:00 in Room Bush House (S) 2.01.

The Wehrl entropy problem: mathematical physics meets complex analysis and representation theory

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.

About the speaker: Professor Rupert Frank received his PhD in Mathematics from the Royal Institute of Technology in Stockholm. He then held postdoctoral and instructor positions at Princeton University and served as a Professor of Mathematics at Caltech before joining LMU in 2016. He has received numerous prestigious awards and grants. His research focuses on analysis and mathematical physics, particularly in functional inequalities, superconductivity, and semiclassical asymptotics.
