| Apr 5, 2011 at 18:57 | comment | added | GH from MO | Darij Grinberg, thanks a lot! Looking briefly at Kevin Buzzard erratum (www2.imperial.ac.uk/~buzzard/errata.pdf) it seems the error is not serious: the statement can be easily adjusted and it serves the final goal equally well. | |

| Apr 5, 2011 at 12:16 | comment | added | darij grinberg | Sorry for bursting in into something I don't understand, but there was a MO topic about errata in Cassels-Fröhlich and it seemed to say that the Ugly Lemma is wrong. mathoverflow.net/questions/11437/erratum-for-cassels-froehlich | |

| Apr 5, 2011 at 1:18 | comment | added | Pete L. Clark | In fact reduction to pro-$p$-groups is a key argument across Galois cohomology -- for instance even the very definition of cohomological dimension of a profinite group proceeds in this way. If one reads Serre's Galois Cohomology, one sees plenty of this. (As you may well know; the remark is for others too...) | |
