Course/Module description:
Introduction to the basic properties of algebraic numbers.

Course/Module aims:
Getting acquainted with the basic properties of the rings of integers in number fields, decomposition of prime ideals in extensions, p-adic numbers, Hensel's lemma, finiteness of the class number, finite generation of the group of units.
