Generalized Horseshoe Maps part I: limit laws and absolute continuity of physical measure
Abstract
We apply thermodynamic formalism to a generalized horseshoe map. We prove that a tailored anisotropic Banach space with weighted norms yields a spectral gap for the transfer operator, implying the existence of a unique physical measure and limit theorems. Under the virtually expanding condition, this measure is absolutely continuous with respect to Lebesgue measure, with density in the Sobolev space $H^μ$, for some $μ
