Annotation -
Algebraic number theory studies the structure of number fields and forms the basis for most of advanced areas of number theory. Following the lecture Basic algebraic number theory (NMAG472) we will study more advanced topics, in particular (prime) ideals in general Dedekind domains, p-adic numbers and local fields, subgroups of the Galois group, and adeles and applications of class field theory.

Course completion requirements

The course requires an oral exam and credit for the exercises. The credit for the exercises "zapocet" will be awarded for successfully solving several sets of homework problems. Zapocet is not needed for taking the exam.
