On the existence and the enumeration of bipartite regular representations of Cayley graphs over abelian groups
Jia-Li Du, Yan-Quan Feng, Pablo Spiga
In this paper we are interested in the asymptotic enumeration of bipartite Cayley digraphs and Cayley graphs over abelian groups. Let be an abelian group and let be the aut…

A conjecture on bipartite graphical regular representations
Jia-Li Du, Yan-Quan Feng, Pablo Spiga
In this paper we are concerned with the classification of the finite groups admitting a bipartite DRR and a bipartite GRR. First, we find a natural obstruction in a finite group fo…

On Haar digraphical representations of groups
Jia-Li Du, Yan-Quan Feng, Pablo Spiga
In this paper we extend the notion of digraphical regular representations in the context of Haar digraphs. Given a group , a {\em Haar digraph} over is a bipartite digra…
