Projective Representations of Abelian Groups

Representations of Abelian Algebraic Groups

There is reason to believe that there is a close relation between the irreducible representations, in the sense of harmonic analysis, of the group of rational points on a reductive algebraic group over a local field and the representations of the Weil group of the local field in a certain associated complex group. There should also be a relation, although it will not be so close, between the re...

Threshold Representations of Graphs over Abelian Groups

In this paper we consider an extension of the notion of threshold graph to Abelian groups.

From Projective Representations to Quasi-quantum Groups

This is a contribution to the project of quiver approaches to quasi-quantum groups initiated in [13]. We classify Majid bimodules over groups with 3-cocycles by virtue of projective representations. This leads to a theoretic classification of graded pointed Majid algebras over path coalgebras, or equivalently cofree pointed coalgebras, and helps to provide a projective representation-theoretic ...
