Two-dimensional Gauge Theories and Quantum Integrable Systems
Anton A. Gerasimov, Samson L. Shatashvili
In this paper the relation between 2d topological gauge theories and Bethe Ansatz equations is reviewed. In addition we present some new results and clarifications. We hope the rel…
Higgs Bundles, Gauge Theories and Quantum Groups
Anton A. Gerasimov, Samson L. Shatashvili
The appearance of the Bethe Ansatz equation for the Nonlinear Schrödinger equation in the equivariant integration over the moduli space of Higgs bundles is revisited. We argue that…
Towards Integrability of Topological Strings I: Three-forms on Calabi-Yau manifolds
Anton A. Gerasimov, Samson L. Shatashvili
The precise relation between Kodaira-Spencer path integral and a particular wave function in seven dimensional quadratic field theory is established. The special properties of thre…
On Field Theory of Open Strings, Tachyon Condensation and Closed Strings
Samson L. Shatashvili
I review the physical properties of different vacua in the background independent open string field theory. Talk presented at Strings 2001, Mumbai, India, http://theory.theory.tifr…
