Analogues of the vertex‐source pairs of the modular representation theory of finite groups are introduced in order to study injective modules over infinite groups. A simplified analogue of the Green correspondence is established. The analogue of Clifford theory is developed by applying Moody's theorem on G 0 of crossed products to the endomorphism rings of induced modules.
