| Mar 6, 2010 at 22:49 | comment | added | Kevin Buzzard | PS I think underlying my comment is the observation that Q_p is a complete non-arch field, but there are lots of complete non-arch fields. If you want to do arithmetic (e.g. class field theory) then you probably need a Haar measure so you want to assume that your complete non-arch field is locally compact, i.e. the residue field is finite, and then you might want to read Cassels-Froehlich. But if you want to do algebra or analysis then completeness might be all you need, in which case you might want to read BGR instead, which is not about Q_p, but about general complete non-arch fields. | |
