On some representations of Metacyclic groups whose integral forms can be computed from a single residual representation
Bruno Aguiló-Vidal, Luis Arenas-Carmona, Matías Saavedra-Lagos
In a previous work we computed the number of integral forms, over its field of definition, of an irreducible representation of a dihedral group. Here we apply the theory of Bruhat-…

Two dimensional integral representations via branches of the Bruhat-Tits tree
Bruno Aguiló-Vidal, Luis Arenas-Carmona, Matías Saavedra-Lagos
We apply the theory of branches in Bruhat-Tits trees, developed in previous works by the second author and others, to the study of two dimensional representations of finite groups…
