Geometry-Topology Seminar

TIME+DATE : 4:10pm--5:00pm Tue 27 Nov 2018
ROOM : 216 Ritter Hall

TITLE: Lie Representation Theory, Frames, and Wavelets, I: Introduction

SPEAKER: Brent Wessel, SLU

ABSTRACT: An important topic when studying Lie groups is the representation theory behind it and how we can relate representations to orbits of certain actions. I will give an overview of the construction and decomposition of wavelet representations of a certain class of nilpotent groups. These will then be used to develop a Calderon condition for the existence of admissible vectors for these groups. The first talk will be focused on some of the background in Lie and representation theory while the second talk will zoom in on a particular class of examples. Graduate students with first-year analysis, topology, and algebra are encouraged to attend, especially the first talk on the background information.

TIME+DATE: 4:10-5:00pm Wed 11/28

Title: Info session on REU in computational arithmetic dynamics

Speaker: Benjamin Hutz, SLU
