$L_{1}$ Actions and Embeddings of Property A Spaces

Chris Gartland, Ignacio Vergara, Tianyi Zheng

We provide several new characterizations of Property A for bounded degree graphs. In particular, we show that $(X, d)$ has Property A if and only if there is a proper gauge $I ¨ $ suc…

Quasi-isometric rigidity for random subsets in products of trees

Zhiqiang Li, Ranfeng Yu, Tianyi Zheng

In this article, we prove a rigidity result for quasi-isometric embeddings from a random subset $D$ of the product $X$ of two regular trees into $X$ itself. This…

Prime orbit theorems for expanding Thurston maps: LattÃ¨s maps and split Ruelle operators

Zhiqiang Li, Tianyi Zheng

We obtain an analog of the prime number theorem for a class of branched covering maps on the $2$ -sphere $S^{2}$ called expanding Thurston maps, which are topological models of some n…
