Reseach interests:
Algebraic geometry, algebraic number theory, integrable systems, higher local fields, valuation theory My major research field at present time is the algebraic theory of integrable systems. Since 2002, together with colleagues from the Mathematical Institute of the Russian Academy of Sciences, as well as with colleagues from Germany (Humboldt University of Berlin, Cologne University), I developed the theory of higher-dimensional Krichever correspondence, which is a generalization of the well-known algebraic theory of the KP equation, and which connects many modern areas of mathematics. The results obtained on this topic from 2002 to 2016 formed the basis of my doctoral dissertation "Torsion free sheaves on varieties and integrable systems". In particular, we developed an approach to a solution of the well-known classification problem of commuting rings of partial differential or differential-difference operators, as well as an approach to the study of their isospectral deformations, based on the study of spectral sheaves on projective algebraic varieties. In the framework of this approach, using fundamentally new algebraic-geometric and number-theoretic ideas and constructions developed by the school of A.N. Parshin, we investigated the geometric spectral data of a wide class of well-known examples of algebraically integrable systems; commutative subalgebras of operators in two variables were classified in terms of geometric spectral data; multidimensional analogues of the KP hierarchy were proposed, explicit isospectral deformations of well-known examples of algebraically integrable Calogero-Moser system with rational potential were found.
