Area of research

My research interests are mostly in geometry and homological algebra of vector bundles and sheaves on algebraic, analytic, and symplectic manifolds as well as applications of all this staff to mathematical physics.

  • Helix theory. This is a cohomological technique for orthogonal decompositions of derived and triangulated categories in terms of exceptional bases. It was developed firstly in my PhD theses (1986/87, see also Gorodentsev A.L., Rudakov A.N. Exceptional vector bundles on projective spaces. Duke Math. J. 54 (1987) p.115-130) in order to describe exceptional vector bundles on Fano varieties. Now the helices are quite popular as one of "mirror symmetry bypasses" between algebraic geometry of coherent sheaves and differential geometry of Picard - Lefschetz pencils.

    Mukai lattices    (Transparencies of my talk at the workshop GEOQUANT-2013, Wien, August 27, 2013)


ALAG. This is an abbreviation for Abelian Lagrangian Algebraic Geometry developed by A.N.Tyurin (see for example math.AG/9902027 and math.AG/9909094) as a geometrical framework for geometric quantization.

  • t-stability. A concept of stability comes from Geometric Invariant Theory where it is used to construct compact orbit spaces for algebraic group actions. t-stability generalizes this approach in a context of generic linear triangulated categories. This allows to consider moduli space problems in very general setup.

    "t-stabilities and t-structures on triangulated categories" (joint with S.A.Kuleshov and A.N.Rudakov): in english and in russian.
    "On finest and modular t-stabilities" (joint with S.A.Kuleshov, in english).


  • Syzygies of projective varieties. There are classical problems of geometry and homological algebra: how to describe a minimal free resolution for the graded coordinate algebra of projective variety in the category of modules over the polynomial ring, and what kind of extra algebraic structures does this resolution admit.

    "On syzygies of highest weight orbits" (joint with A.S.Khoroshkin and A.N.Rudakov, in english). We study a minimal resolution for the coordinate algebra of projective orbit of the highest weight vector in an irreducible representation of semisimple complex Lie group. We show that the syzygies are isomorphic to the cohomologies of appropriate graded Lie superalgebra and illustrate this by several examples including the complete computation of syzygies for grassmannians Gr(2,N) in the standard Plucker embedding.

HSE Staff Members Awarded Status of Tenured Professor

On June 22, several HSE lecturers and staff members were awarded the status of Tenured Professor at a meeting of HSE Academic Council. Sixteen HSE staff members became Distinguished Professors at the Higher School of Economics for the first time.

Springer Nature, HSE and Skoltech to Publish Book Series in Mathematics

Moscow Lectures, a new series of books in English, is set to be published by Springer Nature. The series is issued jointly by HSE and Skoltech, and its Editor-in-Chief is Alexey Gorodentsev, Professor at the HSE Faculty of Mathematics. Twelve volumes are currently in preparation and the first volume will be published at the beginning of June 2018. The series builds on the outstanding research and education in the field of mathematics in Moscow. It is aimed at graduate and undergraduate students, as well as lecturers and researchers, across the globe.

After Turning Down Offers in New York and Berlin, Chinese Student Pursues Mathematics Training at HSE

For DaoDao Yang, a native of Dali, China, choosing a programme in mathematics came down to the decision of where he felt most challenged and most comfortable. This ultimately meant turning down offers at New York University and the Berlin Mathematical School to accept an offer from the Master’s programme at the Higher School of Economics. In an extensive interview with the HSE news service, Dao Dao recently spoke about what led him to choose HSE for his postgraduate study; his impressions of the programme, its professors and his fellow students; and his future plans.

'I’m Glad I Listened to My Heart'

A career in science and technology might sound appealing to the average Russian, but a recent survey showed that most Russians believe men are better suited for this line of work than women. The young women interviewed for this story, a mathematician and a programmer, are of a different opinion.

‘Studying with Enthusiastic People Around is Fun’

In 2015 eight graduates from the HSE Faculty of Mathematics started PhD programmes at MIT, McGill, Caltech, Pennsylvania State University and other top universities. HSE 4th year student Dmitry Pirozhkov who has got a place at Columbia University talked to the HSE News Service about how to get onto a prestigious PhD programme and about his expectations and academic plans.
