Two simultaneous actions of big mapping class groups
Juliette Bavard, Alden Walker
We study two actions of big mapping class groups. The first is an action by isometries on a Gromov-hyperbolic graph. The second is an action by homeomorphisms on a circle in which…
The Gromov boundary of the ray graph
Juliette Bavard, Alden Walker
The ray graph is a Gromov hyperbolic graph on which the mapping class group of the plane minus a Cantor set acts by isometries. We give a description of the Gromov boundary of the…
Stable immersions in orbifolds
Alden Walker
We prove that in any hyperbolic orbifold with one boundary component, the product of any hyperbolic fundamental group element with a sufficiently large multiple of the boundary is…
Stable commutator length in free products of cyclic groups
Alden Walker
We give an algorithm to compute stable commutator length in free products of cyclic groups which is polynomial time in the length of the input, the number of factors, and the order…
