Finite direct-product quotients and uniform Kazhdan constants
Jvbin Yao
We prove that the uniform Kazhdan constant of a finitely generated group vanishes whenever admits finite quotients that are direct products of arbitraril…

Entropy on Homogeneous Spaces and Classification Results for Subgroups with the Pair Rapid Decay Property
Jvbin Yao
We study pair rapid decay for homogeneous spaces \(G/H\) and its applications to random walks and subgroup structure. The entropy framework for groups with rapid decay is extended…

Coarse Geometry of Free Products of Metric Spaces
Qin Wang, Jvbin Yao
Recently, a notion of the free product of two metric spaces and has been introduced by T. Fukaya and T. Matsuka. In this paper, we study coarse geometric permane…
