Dear all,
 
Next week we will hold the first regular meeting of the Horowitz
seminar on Probability, Ergodic Theory and Dynamical Systems for the
spring semester. We are happy to have:
 
Speaker: Bryna Kra, Northwestern University
Title: Rectangular tiling factors of R^d actions
 
Date: Monday, March 4
Time: 14:30
Place: Schreiber 309
 
Abstract:
We study the space of tilings of R^d for a collection of
d-dimensional rectangles. Rudolph showed that there exist 2^d such
tiles such that any free measure preserving R^d action has a tiling
from this space as a factor map, and we show that d+1 tiles suffices.
Furthermore, by studying the geometric properties of the tilings in
R^2, we show that this result is sharp in two dimensions. This is
joint work with A. Quas and A. Sahin.
 
Best regards,
   Ron
