Title: Antivoltages for groups of small order
Let G be a group. A G-antivoltage is a function from the set of
oriented edges of a graph to G such that the product along any cycle is
not the identity. Given a group G of order up to and including six, we
characterize the graphs that have G-antivoltages and also give the list of
minor-minimal graphs that have no G-antivoltages. This is joint work with
Daniel Slilaty.
