Abstract: CalogeroMoserSutherland manybody systems arose originally in the 1970’s simultaneously in Nuclear Physics, Mathematical Physics and Solid State Physics. Since then they were found in some incarnations in diverse branches of physics and mathematics such as the theory of quantum Hall effect, YangMills and ChernSimons gauge theories in various dimensions with various amounts of supersymmetry, noncommutative geometry, topology of Hilbert schemes, geometric representation theory, GromovWitten invariants, theory of symmetric functions, SLE, Random Matrix theory, collective field theory and random geometries.
The aim of the seminar series is to review and explore these connections.

Abstract: I’ll discuss general properties of integrals of exponents of polynomial functions on complex algebraic varieties, and infinitedimensional generalizations. In particular, I’ll give a new interpretation of the solution of Hitchin equation as semiinfinite cohomology.
