Finite rigid sets in curve complexes
(World Scientific Pub Co Pte Lt, 2013-06-01)We prove that curve complexes of surfaces are finitely rigid: for every orientable surface S of finite topological type, we identify a finite subcomplex X of the curve complex C(S) such that every locally injective simplicial ... -
Injections of mapping class groups
(Mathematical Sciences Publishers, 2009-07-02)We construct new monomorphisms between mapping class groups of surfaces. The first family of examples injects the mapping class group of a closed surface into that of a different closed surface. The second family of examples ... -
Simplicial embeddings between pants graphs
(Springer Nature, 2009-06-09)We prove that, except in some low-complexity cases, every locally injective simplicial map between pants graphs is induced by a pi (1)-injective embedding between the corresponding surfaces.
