Departments

Department of Mathematical Sciences

The teachers and associates of the department were involved in research in mathematical calculus (the theory of summability), functional analysis (linear operators), algebra (group theory), geometrical theory of complex function unknowns,mathematical programming - non-linear programming, mathematical modeling, mathematical cybernetics, technical cybernetics, discrete mathematics (theory of automation, theory of functional systems, theory of Boole functions, combinatorial analysis), informatics and the mathematical theory of intelligent systems.

The teachers of the department, in cooperation with the Mathematical Institute of the Serbian Academy of Sciences and Arts, have been organizing a seminar on the theory of automation for several years, and a seminar on the theory of automation and image recognition.

The department has developed institutional scientific and research cooperation with the Department of Discrete Mathematics, and later with the Department of Mathematical Theory of Intelligent Systems at the Faculty of Mechanics and Mathematics, Moscow State University "M. V. Lomonosov".
