Borel-Weil-Bott theorem for algebraic supergroups and weak BGG reciprocity
Dec 25, 14:30—15:30, 2018, Math -101
Speaker
Vera Serganova (University of California, Berkeley)
Abstract
We will review some results about superanalogue of Borel-Weil-Bott theorem, explain the role of Weyl groupoid and prove a weak version of BGG reciprocity. Then we illustrate how BGG reciprocity can be used for computing the Cartan matrix of the category of finite dimensional representations of the nontivial central extension of the periplectic supergroup P(4).

Speaker

Abstract
בהרצאה נדבר על הצגות של חבורות (ולא רק חבורות). תורת ההצגות היא המשך טבעי למושג “פעולה של חבורה על קבוצה”, והוא בא לבטא את הקשר בין חבורות לבין סימטריות של אובייקטים שונים.

Support varieties for supergroups
Dec 26, 15:10—16:25, 2018, -101
Speaker
Vera Serganova (UC Berkeley)
Abstract
We define a functor from the category of representations of algebraic supergroups with reductive even part to the category of equivariant sheaves and show several applications of this construction to representation theory.
