Some Generic Properties of Partially Hyperbolic Endomorphisms

Abstract

In this work, we deal with a notion of partially hyperbolic endomorphism. We explore topological properties of this definition and we obtain, among other results, obstructions to get center leaf conjugacy with the linear part, for a class of partially hyperbolic endomorphism $C^1-$sufficiently close to a hyperbolic linear endomorphism. Indeed such obstructions are related to the number of center directions of a point. We provide examples illustrating these obstructions. We show that for a manifold $M$ with dimension $n\ge 3,$ admitting a non-invertible partially hyperbolic endomorphisms, there is a $C^1$ open and dense subset $\mathcal{U}$ of all partially hyperbolic endomorphisms with degree $d\ge n,$ such that any $f\in \mathcal{U}$ is neither $c$ nor $u$ special.
