Abstract:

In this talk, we introduce the i-Hall algebra of Jordan quiver and connections to the deformed Hall-Littlewood functions (can be viewed as the universal characters of type C), adding a new chapter to the classic constructions of Steinitz, Hall, and Macdonald. This result is applied for the geometric realization of Drinfeld type presentation of affine quantum groups. It is joint work with Shiquan Ruan and Weiqiang Wang.
