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.
