Semantic Factorization and Descent
[OWP-2023-05] (Mathematisches Forschungsinstitut Oberwolfach, 2023-06-19)Let $\mathbb{A}$ be a $2$-category with suitable opcomma objects and pushouts. We give a direct proof that, provided that the codensity monad of a morphism $p$ exists and is preserved by a suitable morphism, the factorization ... -
The Simplicial Complex of Brauer Pairs of a Finite Reductive Group
[OWP-2023-12] (Mathematisches Forschungsinstitut Oberwolfach, 2023-07-17)In this paper we study the simplicial complex induced by the poset of Brauer pairs ordered by inclusion for the family of finite reductive groups. In the defining characteristic case the homotopy type of this simplicial ...
