On faithful projective representations of finite abelian p-groups over a field of characteristic p
Leonid F. Barannyk (2008)
Colloquium Mathematicae
Let G be a noncyclic abelian p-group and K be an infinite field of finite characteristic p. For every 2-cocycle λ ∈ Z²(G,K*) such that the twisted group algebra is of infinite representation type, we find natural numbers d for which G has infinitely many faithful absolutely indecomposable λ-representations over K of dimension d.

On indecomposable projective representations of finite groups over fields of characteristic p > 0
Leonid F. Barannyk, Kamila Sobolewska (2003)
Colloquium Mathematicae
Let G be a finite group, F a field of characteristic p with p||G|, and the twisted group algebra of the group G and the field F with a 2-cocycle λ ∈ Z²(G,F*). We give necessary and sufficient conditions for to be of finite representation type. We also introduce the concept of projective F-representation type for the group G (finite, infinite, mixed) and we exhibit finite groups of each type.

On modular projective representations of finite nilpotent groups
Leonid F. Barannyk, Kamila Sobolewska (2001)
Colloquium Mathematicae
Our aim is to determine necessary and sufficient conditions for a finite nilpotent group to have a faithful irreducible projective representation over a field of characteristic p ≥ 0.

On the isomorphism problem for modular group algebras of elementary abelian-by-cyclic p-groups
Czesław Bagiński (1999)
Colloquium Mathematicae
Let G be a finite p-group and let F be the field of p elements. It is shown that if G is elementary abelian-by-cyclic then the isomorphism type of G is determined by FG.
