Flat covers and factorizations
The flat cover conjecture, saying that every module has a flat (pre)cover, has been recently proved by Bican, El Bashir and Enochs. We relate flat precovers (and cotorsion preenvelopes) to weak factorizations and prove that...

Closure, 2-factors, and cycle coverings in claw-free graphs
In this paper we study cycle coverings and 2-factors of a claw-free graph). For a claw-freeraph G and its closure cl(G), we prove (1) V(G) is covered by k cycles in G if and only if V(cl(G)) is covered by k cycles ...
