 Orateur(s) Jonathan BRUNDAN - Oregon university-- Newton institute Cambridge, Titre Derived equivalences for blocks of Lie superalgebras Date 07/10/2016 Horaire 10:30 à 11:30 Résume I will talk about the problem of classifying blocks of category $\mathcal{O}$ for the general linear Lie superalgebra, both up to Morita equivalence and up to gradable derived equivalence. The analogous problem for a semisimple Lie algebra is usually approached via Soergel’s theory of graded category $\mathcal{O}$. The main point of the talk will be to explain an appropriate substitute in the super case. This comes from the $W$-algebra associated to the principal nilpotent orbit in $\mathfrak{g}$. Categorical Kac-Moody actions in the sense of Rouquier also play a role. Salle salle 2015, 2em étage, Adresse Sophie Germain
