Klíčová slova | flat cover; weak factorization system |
Popis | 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 flat monomorphisms form a left part of a weak factorization system. |
