AI 中文摘要
受Druţu--Sapir工作的启发,我们引入了一个仅依赖于其Cayley-Abels图的相对双曲TDLC群的定义,并证明这个新定义与Arora--Martínez-Pedroja引入的定义等价。然后,我们证明了TDLC群的相对双曲性在拟等距下保持不变。
英文摘要
Motivated by the work of Druţu--Sapir, we introduce a definition of relatively hyperbolic TDLC groups that depends only on their Cayley-Abels graphs and show that this new definition is equivalent to one introduced by Arora--Martínez-Pedroja. Then, we prove that relative hyperbolicity for TDLC groups is invariant under quasiisometry.
