History of the Department

The Department of Mathematical Physics was founded in 1969 by Academician of the USSR Academy of Sciences Prof. V. S. Vladimirov. The first research staff of the Department included several members from the Department of Theoretical Physics (S. S. Khoruzhii and B. M. Stepanov) and from the Department of Differential Equations (V. P. Mikhailov, A. A. Dezin, V. N. Maslennikova, V. S. Vinogradov, and PhD student A. K. Gushchin) of the Steklov Mathematical Institute. In 1970 the Laboratory of Partial Differential Equations was founded in the Department under the direction of V. P. Mikhailov.

Now the research staff of the Department includes 10 permanent researchers: Corresponding Member of the Russian Academy of Sciences Prof. I. V. Volovich (Head of the Department), Professors Yu. N. Drozhzhinov, A. K. Gushchin, M. O. Katanaev, S. V. Kozyrev, N. G. Marchyuk, A. N. Pechen, A. G. Sergeev, V. V. Zharinov, and Dr. A. S. Trushechkin. PhD student: N. B. Il'in.
