Tbilisi Analysis & PDE Seminar
Tbilisi Analysis & PDE Seminar
Dear Colleagues! Institute of Mathematics of the University of Georgia is pleased to invite you to the Online Tbilisi Analysis & PDE Seminar. The seminar is held bi-weekly on Mondays at 20:00 local time in Tbilisi (compare to your local time https://www.timeanddate.com/worldclock/georgia/tbilisi).
Seminar on February 21, 2023
Speaker: Jean Lagacé, King’s College London, UK; https://lagacejean.github.io/
The title of the lecture: “Spectral Geometry on rough spaces”
Abstract: Spectral geometry is concerned with studying the spectrum (the eigenvalues) of differential operators (like the Laplacian) on surfaces and manifolds, and relating that spectrum with the geometry of the underlying space. Many tools, for instance, pseudo-differential calculus and microlocal analysis, have been developed over the years to study the spectrum when everything is smooth. In this talk, I will focus on the asymptotic distribution of eigenvalues (Weyl’s Law), and explain what we can keep when we do not assume the smoothness of the underlying space. Special attention will be given to the Steklov problem.
This is joint work with Mikhail Karpukhin (University College London) and Iosif Polterovich (Université de Montréal).
