报告摘要：K-theoretic quasimap theory to Hilbert scheme of points over algebraic surfaces has enormous interaction with the representation theory of the quantum toroidal algebras. Quantum toroidal algebras can be thought of as the quantum deformation of the Lie algebra gl_{\infty}, which plays an important role in the integrable hierarchy theory. In this talk we show that the refined tau-function, which is introduced by Bourgine and Garbili as the solution to the (q,t)-deformed integrable hierarchy, has its universal formula using the techniques of K-theoretic stable envelopes. This is a joint work with Hunter Dinkins.
