  • Abstract: Thompson’s groups, introduced by Thompson in 1965, have had a lot of attention in the last fifty years. Being finitely presented, a natural question is to compute their Dehn function. All three groups are conjectured to have quadratic Dehn function; this conjecture was confirmed for Thompson’s group F by Guba in 2006. During this talk, we show how to deduce from Guba’s result that Thompson’s group T has quadratic Dehn function as well.
