摘要:

本文研究强传递自同态 $f$ 的热力学形式,重点关注所有扩张测度构成的集合。当 $f$ 是定义在黎曼流形上的非平坦 $C^{1+}$ 映射时,这些测度是所有 Lyapunov 指数均为正的不变概率测度。给定一个 Hölder 连续势函数 $φ$,我们证明了在扩张测度空间中平衡态的唯一性。此外,我们表明,如果存在一个在扩张测度空间上使熵最大化的扩张测度 $μ$,则对于任意具有小振幅 $\text{osc }φ=\supφ-\infφ$ 的 Hölder 连续势函数 $φ$,扩张测度空间上都存在且唯一存在平衡态 $μ_φ$。作为应用,我们证明了 Collet-Eckmann 二次映射对 Hölder 势函数不存在相变,并表明对于 Viana 映射,每个振幅足够小的 Hölder 连续势函数都具有唯一平衡态。

英文摘要:

In this paper we study the thermodynamic formalism of strongly transitive endomorphisms $f$, focusing on the set all expanding measures. In case $f$ is a non-flat $C^{1+}$ map defined on a Riemannian manifold, these are invariant probability measures with all its Lyapunov exponents positive. Given a Hölder continuous potential $φ$ we prove the uniqueness of the equilibrium state among the space of expanding measures. Moreover, we show that the existence of an expanding measure $μ$ maximizing the entropy on the the space of expanding measures implies the existence and uniqueness of equilibrium state $μ_φ$ on the space of expanding measures for any Hölder continuous potential $φ$ with a small oscillation $\text{osc }φ=\supφ-\infφ$. As some applications, we prove that Collet-Eckmann quadratic maps does not admit phase transition for Hölder potential, and show that for Viana maps and every Hölder continuous potential of sufficiently small oscillation has a unique equilibrium state.
