Abstract

Brown has defined generalised Thompson’s groups Fn, Tn, Vn where n is an integer at least 2 and Thompson’s groups F=F2, T=T2, V=V2 in the 80’s. Burillo, Cleary and Stein have found that there is a quasi-isometric embedding from Fn to Fm where n and m are positive integers at least 2. We show that there is a quasi-isometric embedding from Tn to T2 for any n2 and no embeddings from T2 to Tn for n3.
