Free modules are not reflexive
editFor a free module being reflexive is equivalent to being finitely generated. AlexShamov (talk) 05:23, 13 October 2014 (UTC)
- Good catch, noticing the problematic claim about reflexivity. I think, rather than cramming it into a parenthetical comment, it should just be a separate line. I did so in an edit, but I forgot to explain myself in the edit summary. Rschwieb (talk) 13:26, 13 October 2014 (UTC)
