Orbits of subgroups of codimension one to four of the Iwahori group in the affine flag variety of
Claude Eicher
We describe how each finite dimensional Schubert cell in the affine flag variety of decomposes into orbits for a chain of subgroups of codimension one to four of the…
On a Gelfand-Tsetlin representation of in the space of sections of a local system with two monodromy parameters
Claude Eicher
We construct a Gelfand-Tsetlin representation of in the space of sections of a local system. The local system lives on an open part of the flag variety given by t…
Twisted -module extensions of local systems on a certain subvariety isomorphic to of the affine flag variety of
Claude Eicher
We introduce a family of rank-one local systems in the category of twisted -modules on a certain subvariety isomorphic to of the affine fla…
Projective lines in the affine flag manifold with given tangent root vector
Claude Eicher
We first describe the tangent space to the affine flag manifold associated to a simple algebraic group over at the distinguished point starting from standard definitio…
Relaxed Highest Weight Modules from -Modules on the Kashiwara Flag Scheme
C. Eicher
The relaxed highest weight representations introduced by Feigin et al. are a class of representations of the affine Kac-Moody algebra , which do not have a h…
Cohomology of twisted -modules on obtained as extensions from
Claude Eicher
We construct twisted -modules on the projective line that are equivariant for the action of the diagonal torus subgroup of . In the most interesti…
