Course aims

To get acquainted with the basic terms in algebra, which are necessary part of the higher education in mathematics.

Brief description of the course

The topics of this course are: Concept of an algebraic operation. Algebraic structures with one binary algebraic operation (groupoid, semigroup, monoid, group, Abelian group). Algebraic structures with two binary algebraic operations (ring, field, algebra). Substructures (at least subspace of the linear space). Finding roots of complex numbers. Roots of unity. Solving the cubic and quartic equations. Concept of a polynomial. Roots and factors of polynomials. Bézout’s theorem. Greatest common divisors of polynomials and the Euclidean algorithm. Interpolation problem (interpolation polynomials of Newton and Lagrange). Derivative of a polynomial, multiple factors and irreducible factors. Rational fractions. Decomposition of the polynomial into irreducible factors. Irreducibility criteria for polynomials with integral and rational coefficients. Viète’s formulas. Real and complex roots of polynomials. Fundamental theorem of algebra. Polynomials in several variables, symmetric polynomials and the fundamental theorem of symmetric polynomials. Power sums. Resultant and discriminant of polynomials. Elimination problem.
