Crossed products of \(p\)-groups and Green's indecomposability theorem
Green's indecomposability theorem states that induction of modules preserves absolute indecomposability under certain circumstances. The authors present a version of this theorem for arbitrary indecomposable modules. This is a straightforward consequence of an appropriate description of certain crossed products of \(p\)-groups.
