An embedding theorem for automorphism groups of Cartan geometries
Uri Bader, Charles Frances, Karin Melnick
We prove a theorem relating the automorphism group of a Cartan geometry to the group on which the geometry is modeled: a component of the adjoint representation of the first embeds…

Geometric representations of GL(n,R), cellular Hecke algebras and the embedding problem
Uri Bader, Uri Onn
We study geometric representations of GL(n,R) for a ring R. The structure of the associated Hecke algebras is analyzed and shown to be cellular. Multiplicities of the irreducible c…
