Microlocal Perverse Sheaves
S. Gelfand, R. MacPherson, K. Vilonen
Microlocal perverse sheaves form a stack on the cotangent bundle of a complex manifold that is the analogue of the stack of perverse sheaves on the manifold itself. We give an embe…
On the geometry of nilpotent orbits
Wilfried Schmid, Kari Vilonen
In this paper we obtain various results about the geometry of nilpotent orbits. In particular, we obtain a better understanding of the Kostant-Sekiguchi correspondence and Kronheim…
Geometric Methods in Representation Theory
Kari Vilonen
These myh lectures at the Park City conference in 1998.
A geometric Jacquet functor
Matthew Emerton, David Nadler, Kari Vilonen
We describe the Jacquet module functor on Harish-Chandra modules via geometry.
Perverse Sheaves on affine Grassmannians and Langlands Duality
I. Mirković, K. Vilonen
This is an expanded version of the text ``Perverse Sheaves on Loop Grassmannians and Langlands Duality'', AG/9703010. The main new result is a topological realization of algebraic…
Whittaker Patterns in the Geometry of Moduli Spaces of Bundles on Curves
E. Frenkel, D. Gaitsgory, K. Vilonen
Let G be a split connected reductive group over a finite field F_q, and N its maximal unipotent subgroup. V. Drinfeld has introduced a remarkable partial compactification of the mo…
