- Course objectives
- Lecture on Galois theory including some of its applications in algebra and geometry. At the end of this course, students should be able to:
understand main results on Galois theory;
explain basic notions and relations among them.
- Field extension: simple algebraic extension, the degree of extension, algebraic and transcendental extension.
- Constructibility by straightedge and compas: imposibility to construct solution of the following geometric problems posed by the Greeks: doubling the cube, trisecting an angle, squaring the circle (without a proof that "pi" is transcendental).
- Normal and separable extension, linear independence of the embeddings of a field, normal closure, Galois correspondence.
- Solvable and simple groups.
- Solvability of algebraic equations in radicals: radical extensions.
- Unified view on solutions of quadratic, cubic and biquadratic equations, construction of an equation of degree five insolvable in radicals over the field of rational numbers.
- Galois group of cyclotomic fields, constructibility of regular polygons by straightedge and compas.
