On uniserial twisted group algebras of finite p -groups over a field of characteristic p

Tilted Algebras and Crossed Products

“…We denote by add(M) the full subcategory of mod A consisting of all summands of a direct sum of copies of a module M. For all unexplained notions and notations, see [1,2,6,11] and [14]. The reader is also referred to the recent papers [3,4] and [17] for a discussion of representation theory problems over crossed product algebras and twisted group algebras.…”
