On the topics of my conversations with Igor Frenkel
Samson L. Shatashvili
This is a summary of my lecture at Igor Frenkel's 70th birthday conference. I give a brief review of my almost forty years of scientific interactions with Igor. I focus here on thr…
Berezin quantization, conformal welding and the Bott-Virasoro group
A. Alekseev, S. Shatashvili, L. Takhtajan
Following Nag-Sullivan, we study the representation of the group of diffeomorphisms of the circle on the Hilbert space of holomorphic functions. Conformal weldi…
Characters, Coadjoint Orbits and Duistermaat-Heckman Integrals
Anton Alekseev, Samson L. Shatashvili
The asymptotics of characters of irreducible representations of a compact Lie group for large values of the scaling factor are given by Duistermaat-Heck…
Coadjoint Orbits, Cocycles and Gravitational Wess-Zumino
Anton Alekseev, Samson L. Shatashvili
About 30 years ago, in a joint work with L. Faddeev we introduced a geometric action on coadjoint orbits. This action, in particular, gives rise to a path integral formula for char…
On spectral cover equations in Simpson integrable systems
Anton A. Gerasimov, Samson L. Shatashvili
Following Simpson we consider the integrable system structure on the moduli spaces of Higgs bundles on a compact Kähler manifold . We propose a description of the corresponding…
Bethe/Gauge correspondence on curved spaces
Nikita A. Nekrasov, Samson L. Shatashvili
Bethe/gauge correspondence identifies supersymmetric vacua of massive gauge theories invariant under the two dimensional N=2 Poincare supersymmetry with the stationary states of so…
