orbit equivalence and wreath products
abstract:
we prove various antirigidity and rigidity results around the orbit equivalence of wreath product actions. let $f$ be a nonabelian free group. in particular, we show that the wreath products $a \wr f$ and $b \wr f$ are orbit equivalent for any pair of nontrivial amenable groups $a$, $b$. this is joint work with robin tucker-drob.
