dc.description.abstract | We characterize those directed and undirected paths P and cycles C which have the property that the class of graphs not admitting a homomorphism into P, respectively C, is closed under taking the product (conjunction). Whether all undirected complete graphs have the property is a longstanding open question due to S. Hedetniemi. | en |
