A class of residually finite groups isomorphic to fundamental groups of VH complexes

In a preprint, Ian Leary inquires whether two hyperbolic finitely presented groups are residually finite. We answer in the affirmative by showing that these groups belong to a class of groups, which we call the polygonal VH or PVH groups. To prove that a group is PVH we introduce a systematic tiling...
