Dynamics Seminar-Spectral Ergodic Theory V

Thursday, 3/4/2021, 4:00pm - 11:59pm

Time and Date: 11 am, Thursday, March 4
Place: Zoom
Speaker: Robbie Robinson
Title: Spectral Ergodic Theory V

Dynamics Seminar-Spectral Ergodic Theory IV

Thursday, 2/25/2021, 4:00pm - 11:59pm

Time: 11 am,  Thursday, February 25
Speaker: Robbie Robinson
Place: Zoom(virtual)
Title: Spectral Ergodic Theory IV
Abstract:  We will introduce ergodic actions of locally compact abelian groups (notable Z^d and R^d) and explain how to use spectral theory to define some of their ergodic properties. Then we begin the proof of the spectral theorem in that context. We will begin with graduate student presentations

University Seminar: Logic Across Disciplines-Cryptographic Constructions

Thursday, 2/18/2021, 9:00pm - 11:59pm

University Seminar: Logic Across Disciplines

Time: Thursday, February 18, 4:00-5:00PM

Place: zoom

Speaker:  Keshav Srinivasan, GWU

Title: Universal Cryptographic Constructions

Dynamics Seminar-Spectral Ergodic Theory III

Thursday, 2/18/2021, 4:00pm - 11:59pm

Time: 11 am,  Thursday, February 18
Speaker: Robbie Robinson
Title: Spectral Ergodic Theory III
Abstract: Spectral measures will be defined for transformations. One version the spectral theorem will be stated. We will also introduce ergodic actions of locally compact abelian groups (notable Z^d and R^d) and explain how to extend spectral theory to such cases.

Dynamics Seminar-Spectral Ergodic Theory II

Thursday, 2/11/2021, 4:00pm - 11:59pm

Time: 11 am,  Thursday, February 11 (2/11/2021 at 11)
Speaker: Robbie Robinson
Title: Spectral Ergodic Theory II

Abstract: Some examples of spectral properties include ergodicity, weak mixing, and mixing. There are also discrete spectrum, singular spectrum, Lebesgue spectrum and various types of mixed spectrum. And of course, there is spectral multiplicity. We first describe what these are for measure preserving transformations, then for flows, and finally for actions of Z^d and R^d.
