The automorphic H-chromatic index of a graph G is the minimum integer m for which G has a proper edge-coloring with m colors which is preserved by a given automorphism H of G. We consider the sum and the product of the automorphic H-chromatic index of a graph and its complement. We prove upper and lower bounds in terms of the order of the graph when H is chosen to be either a cyclic group of prime order or a group of order four.

Abstract

The automorphic H-chromatic index of a graph G is the minimum integer m for which G has a proper edge-coloring with m colors which is preserved by a given automorphism H of G. We consider the sum and the product of the automorphic H-chromatic index of a graph and its complement. We prove upper and lower bounds in terms of the order of the graph when H is chosen to be either a cyclic group of prime order or a group of order four.
