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: Boris Solomyak, University of Washington
Title: Tiling dynamical systems with an infinite invariant measure
Date: Monday, May 30
Time: 14:30
Place: Schreiber 309
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.)
