Title: A geometric realization of the quantum enveloping algebra associated with the circle
Date (JST): Thu, Mar 29, 2018, 15:30 - 17:00
Place: Seminar Room A
Abstract: The aim of the present talk is to introduce a Lie algebra associated with the circle and its quantum enveloping algebra. During the first part, I will use a "friendly" algebraic approach to define the former. In the second part of the talk, I will provide a geometric realization of the latter together with its fundamental (tensor) representations. Such a geometric approach is based on the theory of Hall algebras of (stacky) curves.
