Pseudo-Anosov surfaces and Dynamics in 3-manifolds
arXiv:2503.02873
Abstract
We determine which closed orientable -manifolds admit a self-homeomorphism restricting to a pseudo-Anosov map on an incompressible subsurface , which we call a pseudo-Anosov surface. When is irreducible, we show that the self-homeomorphism of is isotopic rel to a "partially pseudo-Anosov" homeomorphism, a notion that we will introduce. This is motivated by the corresponding results for Anosov tori in irreducible -manifolds, and the connection to partially hyperbolic diffeomorphisms, obtained by F. Rodriguez-Hertz, J. Rodriguez-Hertz and R. Ures.
