Titre Intertwining operators between line bundles on Grassmanians
Date14/01/2013
Horaire14:00 à 15:00
RésumeWe consider GL(n,R)-equivariant maps between global sections of equivariant line bundles on (possibly) different Grassmanians. We fined when such maps exist and show that they are unique up to a constant. The question and the answer can be formulated in quite elementary terms. Time permitting, I will sketch the proof whose main ingredient is the theory of derivatives that was introduced by Bernstein-Zelevinsky over p-adic fields and recently partially extended to Archimedean fields by us. This is a joint work with Siddhartha Sahi.
