Title
Combinatorial invariants of measure equivalence in the presence of negative curvature
Abstract
I will talk about recently work with Camille Horbez, on measure equivalence invariants of certain countable groups acting on combinatorial complexes with certain form of negative curvature or non-positive curvature. This has application to a number of rigidity results in Artin groups, Coxeter groups and Higman groups.
