Geometry/Physics Seminar

Title: Hall Algebras (Pre-talk)
Speaker: Professor Valerio Toledano Laredo
Speaker Info: Northeastern University
Brief Description:
Special Note:

I will review the construction of the Hall algebra H(A) of an abelian category. In examples coming from quivers, H(A) is a quantum group, where the role of the deformation parameter is played by the cardinality q of the field over which A is defined.

I will also explain how one may set q=1 and obtain the enveloping algebras of semisimple Lie algebras.
