The Roquette category of finite $p$-groups
Let p be a prime number. This paper introduces the Roquette category \mathcal{R}_p of finite p -groups, which is an additive tensor category containing all finite p -groups among its objects. In \mathcal{R}_p , every finite p -group P admits a canonical direct summand \partial P , called the edge …
