This paper is concerned with the second Loewy layer of the projective cover of an irreducible KG-module U , where K is a ΓΏeld of prime characteristic p and G a ΓΏnite group such that p||G|. We use elementary cohomological techniques to obtain under certain circumstances a short exact sequence and to
Based on the ideas of Tannaka-KreΔ± Λn reconstruction, we present a categorical construction that assigns to any cleft Hopf algebra inclusion K β¦ H a coquasibialgebra having K\* as a Hopf subalgebra. As a special case, the construction gives an intrinsic connection between the bismash product K#Q and
