Determining the finite subgraphs of curve graphs

Tarik Aougab, Ian Biringer, Jonah Gaster

We prove that there is an algorithm to determine if a given finite graph is an induced subgraph of a given curve graph.

Building hyperbolic metrics suited to closed curves and applications to lifting simply

Tarik Aougab, Jonah Gaster, Priyam Patel +1

Let $γ$ be an essential closed curve with at most $k$ self-intersections on a surface $S$ with negative Euler characteristic. In this paper, we construct a hyperbolic met…

Curves intersecting exactly once and their dual cube complexes

Tarik Aougab, Jonah Gaster

Let $S_{g}$ denote the closed orientable surface of genus $g$ . We construct exponentially many mapping class group orbits of collections of $2 g + 1$ simple closed curves on $S_{g}$ which…

A family of non-injective skinning maps with critical points

Jonah Gaster

Certain classes of 3-manifolds, following Thurston, give rise to a 'skinning map', a self-map of the Teichmüller space of the boundary. This paper examines the skinning map of a 3-…
