Oct 15, 2011 at 22:38 | comment | added | John Pardon | Is there a standard reference for the equivalence of these two versions of cech cohomology? | |
Oct 13, 2010 at 14:04 | comment | added | Greg Kuperberg | What I meant is, the old-fashioned definition is that if you have an inverse limit of nice spaces, you can define the Cech cohomology as the induced direct limit of cohomology groups. The new-fashioned definition is also a direct limit, but using open covers instead. | |
