A generalized Brauer construction and linear source modules

Abstract

For a complete discrete valuation ring O with residue field F, a subgroup H of a. finite group G and a homomorphism φ : H → Ox, we define a functor V → (H, φ) from the category of OG-modules to the category of FNG(H, φ)-modules and investigate its behaviour with respect to linear source modules. © 2000 American Mathematical Society.
