Some generic properties of partially hyperbolic endomorphisms*

Abstract

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 ⩾ 3, admitting a non-invertible partially hyperbolic endomorphisms, there is a C 1 open and dense subset U of all partially hyperbolic endomorphisms with degree d ⩾ n, such that any f ∈ U is neither c nor u special.
