Classification of special Anosov endomorphisms of nil-manifolds

Abstract

In this paper we give a classification of special endomorphisms of nil-manifolds: Let $f:N/\Gamma \to N/\Gamma$ be a covering map of a nil-manifold and denote by $A:N/\Gamma \to N/\Gamma$ the nil-endomorphism which is homotopic to $f$. If $f$ is a special $TA$-map, then $A$ is a hyperbolic nil-endomorphism and $f$ is topologically conjugate to $A$.
