Borel Combinatorics of Schreier Graphs of $Z$ -actions

Su Gao, Yingying Jiang, Tianhao Wang

In this paper we consider the Borel combinatorics of Schreier graphs of $Z$ -actions with arbitrary finite generating sets. We focus mostly on the problem of computing the…

Strong marker sets and applications

Su Gao, Tianhao Wang

We prove the existence of clopen marker sets with some strong regularity property. For each $n \geq 1$ and any integer $d \geq 1$ , we show that there are a positive integer $D$ and a…
