In the present paper, we are concerned with the connectedness of products of arbitrary families of graphs, and the question, first considered in (1, p. 152), of the uniqueness of the decomposition of a graph into indecomposable factors. We also show that the strong ... In graph theory, a graph product is a binary operation on graphs. Specifically, it is an operation that takes two graphs G1 and G2 and produces a graph H with the following properties: • The vertex set of H is the Cartesian product V(G1) × V(G2), where V(G1) and V(G2) are the vertex sets of G1 and G2, respectively. • Two vertices (a1,a2) and (b1,b2) of H are connected by an edge, iff a condition about a1, b1 in G1 and a2, b2 in G2 is fulfilled. clock repair in kc
