The hardest part is to prove the case when after deleting a separating set of size k, exactly one of the components of the remaining graph has fewer than 32k vertices, since the induction assumption does not hold for n<52k. New ideas in the proof are in Lemma 8, Lemma 9. 2. Proof...

We extend results of Ryjáek, Saito, and Schelp (1999) and show that the number of odd components of a 2-factor in a claw-free graph is stable under Ryjáek's closure operation. We also consider conditions that ensure the existence of a pair of disjoint 1-factors in a claw-free ...
