Polynomial functors and quantum symmetric pairs

Date/Time: Monday 2 November, 1.30pm - Algebra and Geometry Seminar

Venue: Zoom

Abstract: Polynomial functors give a useful way to view the (polynomial) representations for general linear groups. I will explain some insights from this functor interpretation of representations, in particular how it displays the stability property of the family GL_n for all n, and present some generalizations of the polynomial functors. The latter arise from a stability property of the quantum groups (quantum deformation of the family GL_n) and certain quantum symmetric pairs. The talk is based on a joint work with Valentin Buciumas.
