The Different and Discriminant

  • Chapter
Algebraic Number Theory

Part of the book series: Graduate Texts in Mathematics ((GTM,volume 110))

Abstract

The study of the different and discriminant provides some information on ramified primes, and also gives a sort of duality which plays a role both in the algebraic study of ramification and the later chapters on analytic duality. It also gives a good method for computing the ring of algebraic integers in a number field, as in Proposition 10.
