Topological similarity in the group of invertible measure-preserving transformations
Abstract: Two elements g and h of a Polish group G are topologically similar if for
every sequence (i_n) of integers, (g^{i_n}) converges to the identity iff (h^{i_n})
converges to the identity. We'll explore this notion in the group of invertible
measure-
preserving transformations, showing connections to mixing properties, centralizers,
and conjugacy classes of transformations.
