Abstract

Using the Penrose transform, we construct analogues of the BGG (BernsteinGelfand-Gelfand) resolutions in certain singular infinitesimal characters in the holomorphic
geometric setting over the Lagrangian Grassmannian. We prove the exactness of the constructed complex over the big affine cell.

Keywords

Bernstein-Gelfand-Gelfand (BGG) complexes; singular infinitesimal character; invariant differential operators; Lagrangian Grassmannian; Penrose transform
