May uses this to some effect in the May ss computing the cohomology of the Steenrod algebra. ('some' means 'I don't remember exactly how useful this is, but there must have been some point to it.') | |

| Aug 19, 2010 at 15:50 | comment | added | Mariano Suárez-Álvarez | No one really computes cohomology using the bar resolution... It is nice to know that one has it available to prove theorems and such, but it is far too big to be of any practical use. I don't think one can «distill» in any sensible sense (that is, without knowing the answer beforehand) the periodic resolution from the bar resolution in the case of cyclic groups. If I recall correctly, the periodic one can be obtained as the Gruenberg resolution for the obvious presentation of cyclic groups (see, e.g., Hilton-Stammbach's book) | |
