Talk:Quasi-Frobenius ring

General recommendations
Hi, I'm aware this page needs many additions. The definition section I think is long enough, but there is plenty of room for compartmentalized sections. If anyone can help contribute new sections on the following topics, that would be great:
 * the Nakayama permutation
 * characterization in terms of annihilator conditions
 * QF rings have self-duality
 * characterization in terms of (semi)reflexive modules
 * lots more I'm sure I've forgotten. Rschwieb (talk) 17:20, 10 May 2011 (UTC)

Just a remark : Under "Notes", it says that QF rings have the property that all their modules can be embedded in a free one. This can be misleading because this is true for all rings in fact (not very efficiently) by taking the free module on all the elements. — Preceding unsigned comment added by BogdanGhe (talk • contribs) 03:30, 22 September 2013 (UTC)
