Working Seminar in Orbit Equivalence and Measured Group Theory

iCal  iCal

Time: 10:00AM - 11:00AM

Location: BLOC 624

Speaker: Robin Tucker-Drob

Title: Introduction to Strong Ergodicity II

Abstract: This will be a continuation of the last talk. I will present the proof of Jones and Schmidt that an ergodic action is not strongly ergodic if and only if it admits a non-trivial homomorphism to the equivalence relation E_0, of eventual equality on Cantor space.


Analysis/PDE Reading Seminar

Time: 4:00PM - 5:00PM

Location: BLOC 624

Speaker: Isaac Harris, TAMU

Title: Some analytical tools for non-linear eigenvalues applied to inverse scattering.

Abstract: We will discuss some results pertaining to non-linear eigenvalue problems and how they can be used to study the transmission eigenvalue problem that comes from inverse scattering. Transmission eigenvalue problems are a new class of eigenvalue problems that are non-selfadjoint and non-linear (in the proper function spaces) which can not be handled by standard theory (such as the Hilbert–Schmidt theorem).
