Tensor product of graphs

Operation in graph theory

In graph theory, the tensor product G × H of graphs G and H is a graph such thatthe vertex set of G × H is the Cartesian product V(G) × V(H); and vertices (g,h) and (g',h' ) are adjacent in G × H if and only if g is adjacent to g' in G, and h is adjacent to h' in H.
