Subject:

A stability of a soliton solution of the cubic nonlinear Schroedinger equation is defined and proved. A stability of solitary waves that do not vanish as the spatial variable tends to infinity for similar equations of a more general kind is studied. The problem of constructing invariant measures associated with energy for the nonlinear Schroedinger equation is solved partially. Invariant measures associated with higher conservation laws are constructed for the Korteweg–de Vries and nonlinear Schroedinger equations. The property of being a basis in $L_2$ is proved for eigenfunctions of simplest nonlinear Sturm–Liouville-type problems. In addition, the well-posedness of a problem for the Vlasov equation with a regular potential, when one has a joint distribution of particles in a coordinate space, is shown and (with V. Zh. Sakbaev) questions of the existence of radial solutions for superlinear elliptic second-order boundary-value problems in a spherical layer in the case when coefficients depending only on the spatial variable in the equation change sign and questions of constructing of wave multifunctions in multiply connected domains are considered.

Biography

Graduated from Faculty of Computational Mathematics and Cybernetics of M. V. Lomonosov Moscow State University (Department of computational mathematics) in 1978. Ph.D. thesis was defended in 1982. A list of my works contains about 50 titles. Since 1986 I have been working at the Bogoliubov Laboratory of Theoretical Physics of the Joint Institute for Nuclear Research, currently in a group of mathematical physicists.
