Classification box thought, the research of abelian extensions of algebraic quantity fields, is likely one of the greatest branches of algebraic quantity idea. It brings jointly the quadratic and better reciprocity legislation of Gauss, Legendre, and others, and enormously generalizes them. a few of its outcomes (e.g., the Chebotarev density theorem) follow even to nonabelian extensions.
This booklet is an obtainable advent to category box thought. It takes a standard technique in that it provides the worldwide fabric first, utilizing the various unique suggestions of facts, yet in a way that's purifier and extra streamlined than so much different books in this topic.
It will be used for a graduate path on algebraic quantity thought, in addition to for college kids who're drawn to self-study. The booklet has been class-tested, and the writer has integrated routines during the textual content.
