On the denseness of distal points
Su Gao, Hanfeng Li, Ruiwen Li
The paper answers a question about when distal points are dense in the Bernoulli shift over a countable discrete group, characterizes groups for which almost automorphic points beh…
Extremely amenable automorphism groups of countable structures
Mahmood Etedadialiabadi, Su Gao, Feng Li +1
In this paper we address the question: How many pairwise non-isomorphic extremely amenable groups are there which are separable metrizable or even Polish? We show that there are co…
Orbit equivalence of Cantor minimal systems
Su Gao, Ruiwen Li, Yiming Sun
In this paper we study the descriptive complexity of the topological orbit equvalence relation for some Borel classes of Cantor minimal systems. Specifically, we study the Borel cl…
Toeplitz subshifts of finite rank
Su Gao, Ruiwen Li, Bo Peng +1
In this paper we study some basic problems about Toeplitz subshifts of finite topological rank. We define the notion of a strong Toeplitz subshift of finite rank by combining t…
