| Oct 13, 2016 at 17:00 | comment | added | John Rognes | @Bombyx mori: By using Steenrod's term "convenient" about the category CGH, I meant to say that it is already a rather well-behaved category. The need to change the underlying point sets of some colimits (compared to those in CG or Top) is a drawback, but a minor one. By "even better behaved" I meant to say that CGWH has the good properties of CGH, plus better point set behavior for colimits. I should perhaps have started by emphasizing the good properties of CGH more explicitly than I did by saying "convenient", but given the topic of the question I probably thought this was clear. | |
