### Quantitative Recurrence Properties for Systems with Non-uniform Structure

#### Abstract

Let $X$ be a subshift with non-uniform structure, and $\sigma \colon X \to X$ be a shift map. Further, define $R(\psi) := \{x \in X: d(\sigma^{n}x,x) \lt \psi(n) \textrm{ for infinitely many } n\}$ and $R(f) := \left\{ x \in X: d(\sigma^{n}x,x) \lt e^{-S_{n} f(x)} \textrm{ for infinitely many } n \right\},$ where $\psi \colon \mathbb{N} \to \mathbb{R}^{+}$ is a nonincreasing and positive function and $f \colon X \to \mathbb{R}^{+}$ is a continuous positive function. In this paper, we give quantitative estimates of the above sets, that is, $\dim_{H} R(\psi)$ can be expressed by $\psi$ and $\dim_{H} R(f)$ is the solution of the Bowen equation of topological pressure. These results can be applied to a large class of symbolic systems, including $\beta$-shifts, $S$-gap shifts, and their factors.
