# Quantization of Integrable Systems and Four Dimensional Gauge Theories

@article{Nekrasov2010QuantizationOI, title={Quantization of Integrable Systems and Four Dimensional Gauge Theories}, author={Nikita A. Nekrasov and Samson L. Shatashvili}, journal={arXiv: High Energy Physics - Theory}, year={2010}, pages={265-289} }

We study four dimensional N=2 supersymmetric gauge theory in the Omega-background with the two dimensional N=2 super-Poincare invariance. We explain how this gauge theory provides the quantization of the classical integrable system underlying the moduli space of vacua of the ordinary four dimensional N=2 theory. The epsilon-parameter of the Omega-background is identified with the Planck constant, the twisted chiral ring maps to quantum Hamiltonians, the supersymmetric vacua are identified with…
