WebThe strong product is one of several different graph product operations that have been studied in graph theory. The strong product of any two graphs can be constructed as the union of two other products of the same two graphs, the Cartesian product of graphs and the tensor product of graphs. WebAbstract. This work extends the results of M. Rosenfeld [6] on universal graphs with respect to the strong graph product.

WebMay 10, 2024 · Colouring Strong Products. Louis Esperet, David R. Wood. Recent results show that several important graph classes can be embedded as subgraphs of strong products of simpler graphs classes (paths, small cliques, or graphs of bounded treewidth). This paper develops general techniques to bound the chromatic number (and its popular … WebJan 1, 1980 · Regarding the strong product, up to our knowledge, there are no general upper bounds. Nevertheless, the following results study the chromatic number of the strong product of cycles,... In graph theory, the strong product is a way of combining two graphs to make a larger graph. Two vertices are adjacent in the strong product when they come from pairs of vertices in the factor graphs that are either adjacent or identical. The strong product is one of several different graph product operations that … See more The strong product G ⊠ H of graphs G and H is a graph such that the vertex set of G ⊠ H is the Cartesian product V(G) × V(H); and distinct vertices (u,u' ) and (v,v' ) are adjacent in G ⊠ H if and only if: u = v and u' is … See more Every planar graph is a subgraph of a strong product of a path and a graph of treewidth at most six.
