To provide the students an introduction to Galois Theory, and the ability of solving easy exercises on extensions of fields.

The course is an introduction of Galois Theorem. First, we will introduce algebraic extensions of fields, and then we will focus on Galois extensions and associated Galois groups. After proving the fundamental theorem of Galois Theory, we will aim at the characterization of those algebraic equations which are solvable via radicals. Finally, we will introduce the ring of algebraic integers of a number field.

- Fields and extensions of fields
- Algebraic closure of a field

- Fundamental Theorem of Galois Theory
