Abstract

Because of its applications in network theory, the wide diameter of graphs has been studied extensively in recent years. It is still an open problem to compute the wide diameter of Cayley graphs. This paper investigates the wide diameter of Cayley graphs of ℤm, the cyclic group of residue classes modulo m. It is proved that the k-wide diameter of the Cayley graph Cay (Zm, A) generated by a k-element set A is d + 1 for k = 2 and ≤ d + 1 for k = 3, where d is the diameter of Cay (ℤm, A).
