MSC IN MATHEMATICS | ||||||||||

The two-year MSc program in Mathematics provides a profound knowledge of mathematics competitive both in the academic and non-academic sectors, covering topics of algebra and number theory, analysis, geometry, probability theory and statistics, discrete mathematics, operations research, stochastics and data science. There is a large flexibility in choosing subjects according to the personal interest of the student. Foundational courses are provided to those who need them. Theoretical courses are taught mainly by internationally recognized scientists of the university. The students may enter leading-edge research projects of the Institute of Mathematics. Completing our program the graduated students have excellent career opportunities in the research sector, universities and research institutes (by becoming PhD students at either our university or some cutting-edge universities in the US or Europe), as well as in the industrial or commercial sector (by getting well-paid jobs that require greater general mathematical knowledge or a strong ability of abstract thinking and problem solving). | ||||||||||

Theoretical foundations (20 ECTS credits). Earlier not completed, prescribed subjects from BSc in Math. One of the following courses related to the main block of Professional subjects is cumpolsory, others are prescribed by the intructor of the student. Those students who – due to a solid theoretical preparation – need less than 20 credits from BSc in Math subjects will obtain the remaining credits by choosing other optional courses of professional character. | 12 | 4 | 4 | |||||||
