# Department of Computational Mathematics

**General description**

The Department of Computational Mathematics is a structural unit of the Institute of Computation Mathematics and Information Technologies of Kazan (Volga Region) Federal University. Jointly with other Institute units the Department provides teaching for students according to the bachelor and master programs in the directions of studying: “Applied Mathematics” and “Applied Mathematics and Informatics”. The Department specializes students in the field of numerical methods and mathematical modeling. The Department has post-graduate programs in the directions of studying: 01.01.07 – computational mathematics, 05.13.18 – mathematical modeling, numerical methods and program complexes. Also the Department gives mathematical and information technologies lessons in other University units. Currently the Department has seventeen teaching staff members, among them there are nine doctors and four candidates of physical and mathematical sciences.

**History**

Department of Computational Mathematics was organized in 1975 under the initiative of Professor A.D. Lyashko (1930–2008) on the base of research seminar which was led by him since 1965. The seminar was specialized in the field of numerical methods for solving nonlinear problems of mathematical physics. Initially, the seminar united researchers of Mechanics and Mathematics Faculty of Kazan State University. After founding the Computational Mathematics and Cybernetics Faculty in 1978 the Department became a structural unit of the Faculty. The research seminar continued to work on the new Faculty engaging in the research most active students. These students after graduation joined the Department. By the end of the seventies the Department became one of the leading scientific centers of the country in the field of numerical methods for solving mathematical physics nonlinear problems. Professor A.D. Lyashko headed the Department until 1998.

From 1998 to 2013 the Department was headed by Professor M.M. Karchevskiy. According to the fast development of computer and information technologies in this period the research topics is also expanded and updated, including current issues of theoretical and applied directions of mathematical modeling and computational mathematics. By now in the Kazan University a scientific school has been established, which is one of the main centers of research in the field of numerical methods for solving problems of mathematical physics and mathematical modeling.

**The information about the Department head**

Since 2013 the Department is headed by O.A. Zadvornov, Doctor of Physical and Mathematical Sciences, Professor. He is a specialist in the field of mathematical modeling and numerical methods for solving nonlinear problems in continuum mechanics. From 1978 to 1984 O.A. Zadvornov studied in the Kazan University at the Faculty of Computational Mathematics and Cybernetics. After the graduation he worked as an assistant at the Department of Computational Mathematics. In 1997 he defended his candidate dissertation (Ph.D. thesis), in 2007 – his doctoral dissertation (D.Sc. thesis). Currently O.A. Zadvornov is a member of the Institute Academic Council, the scientific secretary of the Kazan Federal University D 212.081.21 Dissertation Council. O.A. Zadvornov participated in the organization of Russian and international scientific conferences "Mesh methods for boundary value problems and applications" in Kazan, directed research projects supported by the Russian Foundation for Basic Research.

**Educational activities**

Teachers of the Department are teaching students of the Institute on general disciplines: numerical methods, mathematical physics equations, information technology, computer architecture, the concept of modern science. For Computational Mathematics Department students teachers give lectures and seminars on special disciplines: applied functional analysis, additional chapters of mathematical physics equations, finite difference methods for solving problems of mathematical physics, finite element method. Teachers of the Department supervise the implementation of the course and final qualifying works of bachelors and masters, lead the research work of post-graduate students.
