| Sep 18, 2012 at 6:01 | comment | added | Nunes | Thank you, professor! Sorry, professor! When I say, $ Top_* $, I mean compactly generated spaces ( I am very familiar with this differences, thanks your book ) But I am still not understanding. I thought $ M_f $ is a compactly generated space by the second proposition (pag. 38). Is the inclusion $ X\to X\wedge I_+ $ closed? And does this closure imply $ M_f $ compactly generated? | |
