报告摘要：

We show that for every C^\infty diffeomorphism of a closed Riemannian manifold, if there exists a positive volume set of points with a positive Lyapunov exponent (in a weak sense) then there exists an invariant probability measure with a disintegration by absolutely continuous conditionals on disks subordinated to unstable leaves. As an application, we solve the strong Viana conjecture in any dimension. This is joint work with D. Burguet.
