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 among them.

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. From 2013 to 2019 the Department is headed by Professor O.A. Zadvornov. This period is characterized by structural changes at the university and foundation of the Institute of Computation Mathematics and Information Technologies.  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 2019 the Department is headed by Professor R.Z. Dautov. Rafail Zamilovich Dautov is a Doctor of Physical and Mathematical Sciences and a Professor of the Department of Computational Mathematics. Professor R.Z. Dautov is widely known both in Russia and abroad as a major specialist in the field of numerical methods and mathematical modeling of continuum mechanics problems. He also has a rich and successful experience in solving applied problems in oil production, computation of thin-walled structures, thermal physics, electrophysical methods of flaw detection, etc. He is the author of the well-known books in the field of numerical methods for solving problems of mathematical physics. R.Z. Dautov has a rich experience in teaching at the Institute. He developed a large number of general and special courses, series of tasks widely used by teachers of the Institute for laboratory and practical work. Several candidate and doctoral dissertations in the fields of computational mathematics and mathematical modeling were defended under his supervision and with his active help
