Abstract:
I will discuss how a family of Schur-Jack type polynomials naturally emerges as a representation space for infinite-dimensional quiver Yangian algebras. An initial example would be the affine Yangian of gl1, in which the representation space is Jack polynomials (enumerated by Young diagrams) in time variables, and the generators of the algebra itself are generated by the cut-and-join operator. By analogy with the Cartan classification of Lie algebras, quiver Yangians are defined using a quiver and a superpotential. I will show how free-field representations of Fock-like representations are modified using the simplest examples, that is, how the set of “Young diagrams/time variables/Jack polynomials/cut-and-glue operator” generalizes for quivers beyond the gl1 case.
