在本文中,我们在服从群体行为的背景下建立了紧凑子集拓扑压力的变分原理。准确地说,对于紧凑度量空间上的可数服从群动作,例如 \begin{document}$ G\curvearrowright X $\end{document} ,对于任何潜在的 \begin{document}$ f\in C(X) $\end{document} ,我们定义和研究任意子集上的拓扑压力,并测量任何 Borel 概率度量的理论压力 \begin{document}$ X $\end{document} (不一定不变);此外,我们证明了给定非空紧凑子集 \begin{document}$ K\subseteq X $\end{document} 上的拓扑压力的变分原理。
In this paper, we establish a variational principle for topological pressure on compact subsets in the context of amenable group actions. To be precise, for a countable amenable group action on a compact metric space, say \begin{document}$ G\curvearrowright X $\end{document} , for any potential \begin{document}$ f\in C(X) $\end{document} , we define and study topological pressure on an arbitrary subset and measure theoretic pressure for any Borel probability measure on \begin{document}$ X $\end{document} (not necessarily invariant); moreover, we prove a variational principle for this topological pressure on a given nonempty compact subset \begin{document}$ K\subseteq X $\end{document} .
