Prerequisites:

Algebra and Geometry courses of the first and second years: in particular groups, rings fields and linear algebra. 
Target skills and knowledge:

The classical theory of the fields and the theory of Galois will be presented. In particular: ruler and compass constructions, solubility for radicals of
algebraic equations, field extensions, normality, separability. 
Examination methods:

Written and oral exams 
Assessment criteria:

The knowledge and the ability to apply the notions and results seen during the course will be evaluated. 
Course unit contents:

Polynomials and their roots. Artin theorem on simple extensions. Separable and purely inseparable extensions of fields. Splitting fields. Algebraic closure of a field. Galois extensions. Cyclotomic Extensions. Jordan Holder Theorem. Soluble groups. Fundamental theorem of algebra. Resolubility for radicals. Galois Theorem. Berlekamp algorithm. Cyclic extensions. Dedekind's theorem. Ruler and compass constructions. Galois groups of polynomials up to the fourth degree. 
Planned learning activities and teaching methods:

Frontal lessons, using a tablet. 
Additional notes about suggested reading:

The study material is made up of suggested text books, lesson notes, and any other notes that will be made available on the course website.
