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...

To prove that a group is PVH we introduce a systematic tiling method for the standard 2-complex of the group, and deduce from the work of Daniel Wise that hyperbolic PVH groups are residually finite. === Dans un prépublication, Ian Leary se demande si deux groupes finitement hyperboliques et de présentation finie sont résiduellement finis.
