geometry of nonlinear differential equations; application of homological methods to partial differential equations.
Subject:
A theory of nonlocal symmetries and conservation laws for nonlinear differential equations was constructed (jointly with A. M. Vinogradov). A cohomological theory of recursion operators for symmetries of partial differential equations was constructed. New recursion operators for supersymmetric integrable systems were found (jointly with P. H. M. Kersten).
Biography
Graduted from Faculty of Mathematics and Mechanics of M. V. Lomonosov Moscow State University (MSU) in 1971 (Chair of Higher Geometry and Topology). Ph. D. thesis was defended in 1978. D. Sci. thesis was defended in 1997. A list of my works contains more than 60 titles. Since 1991 had let a research seminar on geometry of differential equations (at MSU until 1997 and at the Independent University of Moscow afterwards).
