Title
Focality and graph isomorphism
Abstract
A graph is focal if the stabiliser of every vertex x fixes exactly one edge not incident with x . It is shown that the problem of testing whether a connected bipartite grpah is focal has the same complexity as the graph isomorphism problem. Several other similar questions are also considered.
