Let G be a finite elementary abelian p-group. Given a 2-cocycle ␣ of G over the field of complex numbers, we show how to construct an irreducible projective representation of G with 2-cocycle in the cohomology class of ␣. Let S be a 2 ## Ž . subgroup of G of index dividing p . Then we also count

In this paper, we prove that the category TAb of topological Abelian groups is quasi-Abelian. Using results about derived projective limits in quasi-Abelian categories, we study exactness properties of the projective limit functor in TAb. If X is a projective system of TAb indexed by a filtering ord
