Spectral curve duality beyond the two-matrix model
arXiv:1909.02514 · doi:10.1063/1.5094044
Abstract
We describe a simple algebraic approach to several spectral duality results for integrable systems and illustrate the method for two types of examples: The Bertola-Eynard-Harnad spectral duality of the two-matrix model as well as the various dual descriptions of minimal model conformal field theories coupled to gravity.
