The course is also offered to the students of the fields other than those the course is directly associated with.
fields of study / plans the course is directly associated with
  • Mathematics (programme PřF, M-MA, specialization Discrete Mathematics)
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.
