ROCT. Note 2 o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o My e-neurones tell me that I apparently collected a lot of material from previous discussions here: InterSciWiki : Jon Awbrey : Mathematical Notes http://intersci.ss.uci.edu/wiki/index.php/User:Jon_Awbrey/Mathematical_Notes There are excerpts ''Categories for the Working Mathematician'' by Saunders Mac Lane that I posted to various discussion lists back in the days when there was a lot more cross-fertilization between different communities du web than is common these days. InterSciWiki : Jon Awbrey : Mathematical Notes : Category Theory http://intersci.ss.uci.edu/wiki/index.php/User:Jon_Awbrey/Mathematical_Notes#CAT._Category_Theory One could hardly do better than to begin with Mac Lane's book: | Saunders Mac Lane, | Categories for the Working Mathematician, | 2nd edition, Springer, New York, NY, 1997. I'll be busy over the next few days re-formatting those old wiki notes to make them more useful for the sake of our discussions here.
