Course Objectives: | The course aims to develop all the necessary algebraic objects (groups and rings, polynomial rings, fields, field extensions) and their properties whenever needed on the way to solve that classical problem in Galois theory. |
Course Content: | The content of the course consists of cubic and quartic equations, Cardano formulas, The Fundamental Theorem of Algebra, field extensions, finite, normal, separable extensions, fields of characteristic 0 and p, Galois group, Galois extension, The Fundamental Theorem of Galois theory, solvability by radicals, solvable groups, finite fields. |
The students who have succeeded in this course;
1) Will be able to formulate the precise meaning of the solvability problem of polynomial equations by radicals. 2) Will be able to distinguish normal and separable extensions of fields. 3) 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. 4) Will be able to express the solvability of a polynomial equation by radicals using the solvability of its Galois group. 5) Will be able to apply Galois Theory to impossibility proofs of some geometric constructions. |
