Biography
In 1981 he entered the Department of Mechanics and Mathematics of Lomonosov Moscow State University and in 1986 graduated with honors. In 1994, under the leadership of Academician S.P. Novikova defended his thesis on the topic “Sullivans minimal models and smooth differential forms of manifolds”. Since 1989, he has been working at the Chair of Higher Geometry and Topology of the Department of Mechanics and Mathematics of Lomonosov Moscow State University.
The main scientific results:
Narrow in the sense of Zelmanov and Shalev naturally graded Lie algebras of width 3/2 were classified. The problem is solved both in the finite-dimensional and infinite-dimensional cases for the field of reals and for the field of complex numbers.
It is proved that the commutants of the characteristic Lie algebras of the sine-Gordon and Tzitzeika equations are narrow naturally graded Lie algebras of width 3/2 and they are isomorphic to the positive parts of affine Lie algebras of rank two. Thus, both characteristic Lie algebras have slow linear growth.
It is proved that for a compact solvmanifold with a completely solvable Lie group G, the Morse – Novikov cohomology of the solvmanifold G /,, i.e. the cohomology of a de Rham complex with a deformed differential d + w, where w is a closed 1-form, is nontrivial if and only if the cohomology class [w] belongs to some finite subset in the one-dimensional cohomology of the solvmanifold G / Γ defined in terms of the tangent Lie algebra of the group Lee G.
Explicit formulas are found for all the differentials of the Rocha-Caridi-Wallach-Feigin-Fuchs resolution. These formulas are given in terms of the special vectors of Verma modules over the Witt algebra. Explicit formulas are found for an important series of singular vectors. Explicit formulas for the differentials of such a resolvent allow one to calculate the cohomology of the positive part of the Witt algebra with coefficients in its arbitrary module.
Buchstabers hypothesis is proved that cohomology with trivial coefficients of the algebra of vector fields on the line (the positive part of the Witt algebra) is generated by iterated nontrivial higher Massey products of two one-dimensional cohomology classes.
The cohomology of two infinite-dimensional Vergne algebras were calculated. These two algebras are from the Zelmanov-Shalev-Fialovsky classification list of narrow positively graded Lie algebras of maximal class.
In the framework of the theory of filtered deformations of positively graded Lie algebras over a field of characteristic zero: 1) equations are found explicitly defining the variety of Lie algebras of the maximum class (the variety of filiform Lie algebras); 2) it is shown that there exists a bijection between the moduli deformation moduli space of the finite-dimensional factor algebra of the positive part of the Witt algebra and the weighted projective space of dimension four.
