Talk:Free resolution

Projective resolution

I think it would make more sense to define a projective resolution first – it isn't defined anywhere else – as a long exact sequence of projectives, then define and construct free resolution, thereby showing incidentally that a projective resolution always exists. There are properties of a projective resolution that should be mentioned Probably the article should be moved to Projective resolution too. Richard Pinch (talk) 13:30, 15 October 2017 (CEST)
