Isomorphisms and automorphisms of graph products of groups
Amandine Escalier, Camille Horbez
We solve the isomorphism problem for graph products of groups. We give a generating set for the automorphism group of a graph product of groups, generalizing the one given by Laure…

Sofic approximations and quantitative measure couplings
Amandine Escalier
We build quantitative measure subgroup couplings from a Brieussel-Zheng diagonal product to a lamplighter group. We use them to answer the inverse problem of the quantification; na…
