Let G1β and G2β be two undirected nontrivial graphs. The Kronecker
product of G1β and G2β denoted by G1ββG2β with vertex set
V(G1β)ΓV(G2β), two vertices x1βx2β and y1βy2β are adjacent if and
only if (x1β,y1β)βE(G1β) and (x2β,y2β)βE(G2β). This paper presents a
formula for computing the diameter of G1ββG2β by means of the
diameters and primitive exponents of factor graphs.Comment: 9 pages, 18 reference
