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: Boris Solomyak, University of Washington
Title: Tiling dynamical systems with an infinite invariant measure
 
Date: Monday, May 30
Time: 14:30
Place: Schreiber 309
 
Abstract:
We investigate non-primitive, non-minimal tiling substitutions in R^d,
and characterize all "natural" invariant measures for the corresponding
dynamical systems. In many cases, such an invariant measure is unique in
some sense, and it is infinite (but sigma-finite). The first such
example, in 1 dimension ("integer Cantor set") was considered by Alby
Fisher. Our examples include the "Sierpinski gasket" and "Sierpinski
carpet" tilings in the plane. (Joint work with Maria Isabel Cortez.)
 
Best regards,
 
   Ron
