Vergara's conjecture for graphs with independence number two
Let be a graph with independence number , let denote its chromatic number, and let be the complete graph on vertices. A weak immersion of a graph in consists of an injection from to and pairwise edge-disjoint paths in representing the edges of . Vergara's conjecture. Every graph with contains a weak immersion of . The source presents this as the Abu-Khzam–Langston conjecture restricted to graphs of independence number two and notes its equivalence, for graphs with , to the corresponding assertion involving . The status of this named formulation is not separately established in the supplied text.
