    Almost claw-free graphs

  • Original language description

    We say that G is almost claw-free if the vertices that are centres of induced claws K(1,3) in G are independent and their neighborhoods are 2-dominated. Clearly, every claw-free graph is almost claw-free. It is shown that (i) every even connected almostclaw-free graph has a perfect matching and (ii) every nontrivial locally connected K(1,4)-free almost claw-free graph is fully cycle extendable.

    Grafy skoro bez K(1,3)

  • Czech description

    Řekneme, že G je graf skoro bez K(1,3), jestliže uzly G, které jsou středy indukovaných K(1,3) jsou nezávislé a jejich okolí jsou 2-dominovaná. Dokazujeme, že (i) každý sudý souvislý graf skoro bez K(1,3) má perfektní párování, a (ii) každý netriviální lokálně souvislý graf bez K(1,4) a skoro bez K(1,3) je plně kružnicově rozšiřitelný.
