Research Abstract

Our main concern is with the characterization of the image of the Penrose transform by means of a system of partial differential equations on the cycle space. I have extended my previous results (the case that the transformation groups are indefinite unitary groups) to non-tube domains of type AIII ([1]), and also found explicit branching laws of certain singular unitary representations with respect to symmetric pairs by using the Penrose transform.
