- Timetable of Seminar Groups:

*M. Čadek, L. Vokřínek* **Prerequisites**- High school mathematics. Elementary knowledge of algebraic and combinatorial tasks (in the extent of MIN101).
**Course Enrolment Limitations**- 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**- there are 18 fields of study the course is directly associated with, display
**Course objectives**- This is the fourth part of a four semester block of Mathematics. The entire course covers the fundamentals of general algebra and number theory, linear algebra, mathematical analysis, numerical methods, and combinatorics. This semester is concerned with elements of Number theory and its applications and, in the second half, the algebraic concepts and some applications.
**Learning outcomes**- At the end of this course, students should be able to:
understand and use methods of number theory to solve moderately difficult tasks; understand how results of number theory are applied in cryptography; understand basic computational context;

understand algebraic notions and explain general implications and context; **Syllabus**- 1. Number theory (4 weeks) – divisiblity (gcd, extended Euclid algorithm, Bezout); numerics of big numbers (gcd, modular exponential); prime numbers (properties, basic theorems of arithmetics, factorization, prime number testing (Rabin-Miller, Mersenneho prime numbers); congruences (basic properties, small Fermat theorem; Euler theorem; linear congruences; binomial congruences a primitiv roots; discrete logarithm; prime numbers - testing up to AKS, divisors, eliptic curves (introduction); Legendre symbol and the quadratic reciprocity law.
- 2. Number theory applications (2 weeks) – short introduction to asymetric cryptography (RSA, DH, ElGamal, DSA, ECC); basic coding theory (linear and polynomial codes); aplication of fast Fourier transform for quick computations (e.g. Schönhage-Strassen)
- 3. Algebra (7 weeks) – Boolean algebras and lattices, groups, permutations, symetries, modular groups, homomorfisms and factorization, group actions (Burnside lemma); rings and fields (polynomials and their roots, divisibility in integers and in polynomial rings, ideals; finite fields and their basic properties (including applications in computer science; polynomials of more variables (Gröbner basis).
