On a Gelfand-Tsetlin representation of $sl_{3}$ in the space of sections of a local system with two monodromy parameters

Claude Eicher

We construct a Gelfand-Tsetlin representation of $sl_{3}$ in the space of sections of a local system. The local system lives on an open part of the flag variety given by t…

Relaxed Highest Weight Modules from $D$ -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 $sl_{2}^$ , which do not have a h…

Cohomology of twisted $D$ -modules on $P^{1}$ obtained as extensions from $C^{\times}$

Claude Eicher

We construct twisted $D$ -modules on the projective line $P^{1}$ that are equivariant for the action of the diagonal torus subgroup of $S L_{2}$ . In the most interesti…
