Aims |

Completion of the knowledge in number theory, group theory and combinatorics studied in the courses of algebra of previous semesters. |

Content |

1. Induction. Combinatorics: deduction and induction, mathematical induction (different forms) and Peano's axiomatic study of the set of natural numbers, some applications of the induction; arrangements, permutations and combinations - their general form and applications (number of terms in the canonical form of a polynomial, product of binomials, power of a sum).
2. Arithmetic of numbers and polynomials (comparative study): the division algorithm with remainder - proof for integers and for polynomials. 3. Algebraic structures: an elementary construction of rings and fields, the structure of some finite groups, some applications of finite groups (the symmetry group of a figure, the action of a group on a set, the Polya-Burnside counting method). 4. Algebraic equations: the fundamental theorem of Algebra, complex numbers expressible by radicals, formulae for solving the algebraic equations of second, third and fourth degree. |
