Algebra Seminar: Libedinsky -- The anti-spherical category

Nicolas Libedinsky (University of Chile) 

Friday 11 August, 2:30-3:30pm, Place: Carslaw 375 

Title: The anti-spherical category 

Abstract: I will explain the definition of Kazhdan-Lusztig polynomials and its parabolic
version.  I will calculate an example.  Then I will introduce Soergel bimodules, the
anti-spherical category and explain the recent proof (joint with G.  Williamson) of the
positivity of parabolic Kazhdan-Lusztig polynomials for arbitrary Coxeter groups and
arbitrary parabolic subrgoup.
