Title:Penrose transformation on flag domains
View PDF HTML (experimental)Abstract:Building on our recent work we construct the Penrose transformations of the cohomology groups of homogenous line bundles on flag domains $D=G_\R/T$ with $G_\R$ of Hermitian type. We give sufficient conditions for the injectivity of the Penrose transformations, and conditions under which the Penrose transformation of the automorphic cohomology groups on compact quotients of flag domains is an isomorphism. Finally we prove that the higher automorphic cohomology groups of certain homogeneous line bundles are isomorphic to the groups of automorphic forms on the Hermitian symmetric domain.
