Dynamical Systems Seminar- Introduction to billiards

Friday, 2/22/2019, 2:00pm - 11:59pm

Title: Introduction to billiards
Speaker: Robbie Robinson, GWU Math 
Date and Time: Friday, February 22nd, 9:00–10:15am
Place:  Phillips 736

Abstract: We will begin our discussion about the topic of the dynamics of billiards: Think of a billiard (i.e, pool) table whose boundary is a piecewise smooth simple closed curve.

Dynamical Systems Seminar-On Penrose tilings and tiling dynamical systems: VI

Friday, 2/15/2019, 2:00pm - 11:59pm
