Research Field : Integrable systems: Special functions: Mathematical Physics

Research Summary : The traditional term "integrable system" means a mathematical model that admits exact solutions. In many cases, a beautiful mathematical structure lies in such models. I am studying them from various points of view such as discrete, continuous, classical and quantum. Currently, I am working on the quantization of the iso-monodromy equations, their relation to conformal field theories and gauge theories.
