# Events for October 10, 2017 from General and Seminar calendars

## Working Seminar in Orbit Equivalence and Measured Group Theory

**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 Hilbertâ€“Schmidt theorem).
