Geometric Structures - Olga Paris-Romaskevich - Jan 26 - 4:00 pm (Rome Time)

[Miruna - Stefana Sorea]

Dear All, 

this is to announce the next seminar from the series "Geometric
Structures".

Speaker: OLGA PARIS-ROMASKEVICH ( [1]Institut de Mathématiques de
Marseille [1]) [1] 

Title: Tiling billiards in periodic tilings by equal triangles (and
quadrilaterals)

Time: January 26, 2021, 4:00 pm (Rome Time) 

Venue: from remote only, on zoom at this link

Passcode: geometry

Abstract:  
I will make an elementary introduction to tiling billiards -- model of a
light moving through a tiling under refraction laws. 

This class of dynamical systems is new to mathematicians, simple to
define as well as connected to already existing areas of research such
as ergodic theory of interval exchange transformations and Novikov's
problem on plane sections of 3-periodic surfaces. 

I hope you will love it as much as I love it ! 

(Not a very hard) Homework before the talk : 

Watch a following 5-MIN movie (here is a link to Youtube) [3] by a
wonderful mathematician and animator Ofir David [4].
