Abstract

We introduce continuum-wise hyperbolicity, a generalization of hyperbolicity with respect to the continuum theory. We discuss similarities and differences between topological hyperbolicity and continuum-wise hyperbolicity. A shadowing lemma for cw-hyperbolic homeomorphisms is proved in the form of the L-shadowing property and a Spectral Decomposition is obtained in this scenario. In the proof we generalize the construction of Fathi \cite{Fat89} of a hyperbolic metric using only cw-expansivity, obtaining a hyperbolic cw-metric. We also introduce cwN-hyperbolicity, exhibit examples of these systems for arbitrarily large NNN\in\mathbb{N} and obtain further dynamical properties of these systems such as finiteness of periodic points with the same period. We prove that homeomorphisms of S2\mathbb{S}^2 that are induced by topologically hyperbolic homeomorphisms of T2\mathbb{T}^2 are continuum-wise-hyperbolic and topologically conjugate to linear cw-Anosov diffeomorphisms of S2\mathbb{S}^2, being in particular cw2-hyperbolic.
