Weakly amenable groups
arXiv:1609.03634
Abstract
In this paper, a group is called weakly amenable if its left regular representation is not uniformly isolated from the trivial representation. First examples of finitely generated non-amenable weakly amenable groups are constructed.
This is an old paper published in 2002. It was not posted to arXiv at that time. I am now posting some of my old papers in order to make them more accessible
