Abstract: Given a measure &mu on a manifold M , we wish to characterize
all smooth dynamics preserving &mu. We consider measures &mu supported on the
two-torus and study the group of &mu-preserving diffeomorphisms. For &mu invariant
under an Anosov diffeomorphism, we find conditions for which the group of
&mu-preserving diffeomorphisms is `essentially' cyclic.
