Basic notion of the courses of Algebra 1 and Algebra 2:
Grous,Rings and Galoois theory.

The aim of the course is to provide an introduction to commutative algebra e di teoria dei numeri algebrici.

Commutative algebra: Modules over a (commutative) ring and operations on modules; tensor product of modules. Localization of rings and modules. Primary decomposition of ideals. Artinian and Noetherian rings and modules. Dimension theory. Integral dependence and valuations; Dedekind domains. Spectrum of a commutative ring; affine algebraic sets, Noether's normalization lemma and Hilbert's Nullstellensatz.

Number theory
Algebraic numbers, number fields, Fractiomnal ideal and divisors. Class fields. Geometric representations of numbers. Dirichlet Unity theorem. Galos theory for number Fields. Local Fields. Introduction to Minkowsky theory and to quadratic forms over number fields.

The exam will be a hybrid between written and oral examination.
The first part will consist of some written questions and exercises on basic concepts. Some oral questions will then be reserved for further investigation.
