Conjugating automorphisms of graph products: Kazhdan's property (T) and SQ-universality
arXiv:1904.03599
Abstract
An automorphism of a graph product of groups is conjugating if it sends each factor to a conjugate of a factor (possibly different). In this article, we determine precisely when the group of conjugating automorphisms of a graph product satisfies Kazhdan's property (T) and when it satisfies some vastness properties including SQ-universality.
