A recognition theorem for permutation modules over $p$ -groups extending Weiss' Theorem

Marlon Estanislau

Let $G$ be a finite $p$ -group with normal subgroup $N$ , and $R$ a complete discrete valuation ring in mixed characteristic. We characterize permutation $R G$ -modules in terms of mod…

Permutation modules over cyclic $p$ -groups

Marlon Estanislau

Let $G$ be a cyclic $p$ -group for some prime number $p > 0$ and let $R$ be a complete discrete valuation ring in mixed characteristic. In this paper, we present a generalization of t…
