摘要:
我们应用热力学正则化方法于广义鞋形映射。我们证明了一个定制的各向异性Banach空间,带有加权范数,会为转移算子产生谱间隙,从而推导出存在唯一的物理测度。在几乎扩张条件下,该测度相对于Lebesgue测度绝对连续,其密度在Sobolev空间H_μ中,其中μ<1/2。
英文摘要:
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 $μ<1/2$.
