Isomorphism testing for circulant graphs Cn(a,b)
In this paper we focus on connected directed/undirected circulant graphs Cn(a,b). We investigate some topological characteristics, and define a simple combinatorial model, which is new for the topic. Building on such a model, we derive a necessary and sufficient condition to test whether two circulant graphs Cn(a, b) and Cn(a’,b’) are isomorphic or not. The … Read more
