By Jürgen Neukirch, Alexander Schmidt

This moment version is a corrected and prolonged model of the 1st. it's a textbook for college kids, in addition to a reference publication for the operating mathematician, on cohomological issues in quantity conception. In all it's a almost whole remedy of an unlimited array of crucial themes in algebraic quantity thought. New fabric is brought right here on duality theorems for unramified and tamely ramified extensions in addition to a cautious research of 2-extensions of actual quantity fields.
