Equivariant motives and geometric representation theory. (with an appendix by F. Hörmann and M. Wendt)
Wolfgang Soergel, Rahbar Virk, Matthias Wendt
We consider categories of equivariant mixed Tate motives, where equivariant is understood in the sense of Borel. We give the two usual definitions of equivariant motives, via the s…
Proper base change for separated locally proper maps
Olaf M. Schnürer, Wolfgang Soergel
We introduce and study the notion of a locally proper map between topological spaces. We show that fundamental constructions of sheaf theory, more precisely proper base change, pro…
Perverse motives and graded derived category
Wolfgang Soergel, Matthias Wendt
For a variety with a Whitney stratification by affine spaces, we study categories of motivic sheaves which are constant mixed Tate along the strata. We are particularly interested…
Unicity of graded covers of the Category of Bernstein-Gelfand-Gelfand
Michael Rottmaier, Wolfgang Soergel
We show that the standard graded cover of the well-known category of Bernstein-Gelfand-Gelfand can be characterized by its compatibility with the action of the center…
Modular Koszul duality
Simon Riche, Wolfgang Soergel, Geordie Williamson
We prove an analogue of Koszul duality for category of a reductive group in positive characteristic larger than 1 plus the number of roots of . However…
Andersen Filtration and Hard Lefschetz
Wolfgang Soergel
On the space of homomorphisms from a Verma module to an indecomposable tilting module of the BGG-category O we define a natural filtration following Andersen and establish a formul…
