Matroids and isomorphism problems for Bestvina-Brady groups
Yu-Chan Chang, Lorenzo Ruffoni
We propose a factorization of the graph isomorphism problem for Bestvina-Brady groups (BBGs) through matroid theory. In particular, we show that finitely presented BBGs depend on t…

Convex cocompact groups with three-dimensional limit sets
Sami Douba, Gye-Seon Lee, Ludovic Marquis +1
We provide a general construction of convex cocompact hyperbolic reflection groups with three-dimensional limit sets. More precisely, our construction takes as input an arbitrary s…

Incubulable hyperbolic 3-pseudomanifold groups
Jason Manning, Lorenzo Ruffoni
We construct compact hyperbolic 3-manifolds with totally geodesic boundary, such that the closed 3-pseudomanifolds obtained by coning off the boundary components are negatively cur…
