Course Objective

The aim of this course is to introduce fields and Galois theory and some basic results from the following topics: algebraic number theory, cohomology of groups, categories and functors, and homological algebra.

Learning Outcomes of the Course Unit

1   Will be able to use The Fundamental Theorem of Galois Theory to observe the correspondence between intermediate field extensions and subgroups of the Galois group.
2   Will be able to express the solvability of a polynomial equation by radicals using the solvability of its Galois group.
3   Will be able to apply Galois Theory to impossibility or constructability proofs of some geometric constructions.
4   Will be able to understand the motivation for some important concepts in commutative algebra and field theory that comes from algebraic number theory.
5   Will be able to use the projective and injective resolutions to obtain the derived functors Ext and Tor of the functors Hom and tensor product.
