Title: Hidden quantum group structure on solution spaces of certain PDE Systems Abstract: I describe a systematic method for solving PDEs of certain type, which arise in conformal field theory, and in the theory of Schramm-Loewner evolutions, with boundary conditions given by specified asymptotic behavior of the solutions. Our method is a correspondence associating vectors in a tensor product representation of a quantum group to Coulomb gas type integral functions, in which properties of the functions are encoded in natural, representation theoretical properties of the vectors. In particular, this hidden quantum group structure on the solution space of such PDEs enables explicit calculation of the asymptotics and monodromy properties of the solutions. This also leads us to a generalization of the Temperley-Lieb algebra, defined in terms of a diagrammatic representation. This generalized diagram algebra is the commutant algebra of the quantum group, generalizing the quantum Schur-Weyl duality.
