Teaching Language
Italian.
Course Content
The course is an introduction to algebraica number theory. Starting from the definition of algebraic number, we go on studying the basic properties of rings of integers in number fields. In the final part some applications are given
1) Marcus: Number fields
2) Stewart-Tall: Algebraic number theory and Fermat's last theorem
Learning Objectives
The goal of the course is to introduce the students to the basic tools needed to undertake the study of deeper subjects in number theory, algebraic geometry o Galois theory.
