$\Bbb Z^d$-odometers and cohomology

Classification of operator algebras: complexity, rigidity, and dynamics

09 March 14:00 - 15:00

Thierry Giordano - University of Ottawa

$\Bbb Z$-odometers are well-known examples of minimal Cantor systems. In particular, any two orbit equivalent $\Bbb Z$-odometers. In this talk, I will review the construction of $\Bbb Z^d$-odometers and in particular give two equivalent description of $\Bbb Z^d$-odometers to construct orbit equivalent $\Bbb Z^2$-odometers which are not conjugate. This is joint work with I. Putnam and C. Skau
