The infinite associahedron and R.J. Thompson's group T
Ariadna Fossas
In this paper we construct a cellular complex which is an infinite analogue to Stasheff's associahedra. We prove that it is contractible and state that its (combinatorial) automorp…

On the automorphism group of the asymptotic pants complex of a planar surface of infinite type
Ariadna Fossas, Maxime Nguyen
We consider a planar surface Σof infinite type which has the Thompson group T as asymptotic mapping class group. We construct the asymptotic pants complex C of Σand prove that the…
