Tel Aviv University
 
Dear all,
 
This week at the Horowitz seminar on Probability, Ergodic Theory and
Dynamical Systems at Tel Aviv University we are happy to have:
 
Speaker: John Smillie, Cornell University
Title: Do analogs of Ratner's theorems hold for strata of translation
surfaces?
 
Date: Monday, June 3
Time: 14:30
Place: Schreiber 309
 
Abstract:
Questions about polygonal billiards lead to the study of moduli
spaces of translation surfaces or "strata". There are intriguing
parallels between strata and homogeneous spaces and there has been a
fruitful migration of ideas from homogeneous dynamics to "Teichmuller
dynamics" on strata. One pivotal question is the extent to which
Ratner theory applies to strata. I will discuss positive results of
Eskin and Mirzakhani and describe negative results obtained with
Barak Weiss.
 
Best regards,
   Ron
