Geometry and mathematical physics

The theory of integrable systems studies differential equations which are, in a sense, exactly solvable and possess regular behaviour. Such systems play a fundamental role in mathematical physics providing an approximation to various models of applied interest. Dating back to Newton, Euler and Jacobi, the theory of integrable systems plays nowadays a unifying role in mathematics bringing together algebra, geometry and analysis.

The research of the group includes both classical and quantum integrable systems in relation with representation theory and special functions, as well as algebraic, differential and symplectic geometry.
