Abstract : (Joint work with M. Hirayama) The aim of this talk is to obtainan equivalent criterion for certain expansive di®eomorphisms of T2 to admit aninvariant Borel probability measure that is absolutely continuous with respectto the Riemannian volume. Our result is closely related to the well knownLiv·s-Sinai theorem for Anosov di®eomerphisms.
