Condensed configurations and valuative matroid invariants
Jens Niklas Eberhardt
Condensed configurations are compact incidence data obtained by grouping the cyclic flats of a matroid. We show that their inverse incidence matrices give explicit Schubert expansi…
K-motives, Springer Theory and the Local Langlands Correspondence
Jens Niklas Eberhardt
We construct a geometric realization of categories of representations of affine Hecke algebras and split reductive -adic groups via a -motivic Springer theory. We suggest a c…
Standard Extension Algebras I: Perverse Sheaves and Fukaya Calculus
Jens Niklas Eberhardt, Catharina Stroppel
In this first of a series of articles on standard extension algebras we study standard perverse sheaves on varieties with -actions. Based on Braden's hyperbolic local…
K-theory Soergel Bimodules
Jens Niklas Eberhardt
We initiate the study of K-theory Soergel bimodules-a K-theory analog of classical Soergel bimodules. Classical Soergel bimodules can be seen as a completed and infinitesimal versi…
Integral Motivic Sheaves And Geometric Representation Theory
Jens Niklas Eberhardt, Jakob Scholbach
With representation-theoretic applications in mind, we construct a formalism of reduced motives with integral coefficients. These are motivic sheaves from which the higher motivic…
Motivic Springer Theory
Jens Niklas Eberhardt, Catharina Stroppel
We show that representations of convolution algebras such as Lustzig's graded affine Hecke algebra or the quiver Hecke algebra and quiver Schur algebra in (affine) type A can be re…
