Speaker

Bruno Jartoux (BGU)

Colloquium

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).

הזמנה לתורת ההצגות עדכון: ההרצאה נדחתה

Dec 25, 18:15—19:45, 2018, אולם 101-

Speaker

אינה אנטובה

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.

AGNT

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.
