    Factor criticality and matching extension in DCT-graphs

  • Original language description

    The class of DCT-graphs is a common generalization of the classes of almost claw-free and quasi claw-free graphs. We prove that every even (2p+1)-connected DCT-graph G is p-extendable, i.e. every set of p independent edges of G is contained in a perfectmatching of G. This result is obtained as a corollary of a stronger result concerning factor-criticality of DCT-graphs.

    Faktorová kritičnosti a rozšiřitelnost párování v DCT grafech

  • Czech description

    Třída DCT-grafů je společným zobecněním tříd grafů "almost claw-free" a "quasi claw-free". Dokazujeme že každý (2p+1)-souvislý DCT-graf G je p-rozšiřitelný. Tvrzení je důsledkem silnějšího výsledku o faktorové kritičnosti DCT-grafů.
