Abstract
Let be a conservative partially hyperbolic diffeomorphism, which is homotopic to an Anosov automorphism on . We show that the stable and unstable bundles of are jointly integrable if and only if every periodic point of admits the same center Lyapunov exponent with . This implies every conservative partially hyperbolic diffeomorphism, which is homotopic to an Anosov automorphism on , is ergodic. This proves the Ergodic Conjecture proposed by Hertz–Hertz–Ures on .
