Divergence functions of higher-dimensional Thompson's groups

Yuya Kodama

Vol. 333 (2024), No. 2, 309–329
Abstract

We prove that higher-dimensional Thompson’s groups have linear divergence functions. By the work of Druţu, Mozes, and Sapir, this implies none of the asymptotic cones of nV has a cut-point.

Keywords
