Accessibility of Partially Hyperbolic Endomorphisms With 1d Center-Bundles

We prove that partially hyperbolic endomorphisms with one dimensional center-bundles and non-trivial unstable bundles are stably accessible. And there is residual subset R of partially hyperbolic volume preserving endomorphisms with one dimensional center-bundles such that every f ∈ R is stably accessible. In the end, we prove the accessibility of Gan's example.
