The generalized Penrose-Ward transform. (English) Zbl 0581.32035

The first part of this paper brings in the following unifying conceptual set-up: For complex manifolds Z, Y, X and surjective holomorphic mappings \(\mu\), \(\nu\) of maximal rank that embed Y as a submanifold of \(Z\times X\), \(Z\leftarrow^{\mu}Y\to^{\nu}X\) is called a correspondence. The transforms studied by the author transform objects on Z into objects on X. Thus, an analytic cohomology class, or a holomorphic vector bundle, on Z is pulled back to Y (first stage) and then (second stage) a spectral sequence is formed through the direct image of the data on Y obtained from the first stage. The differentials of the spectral sequence are induced from certain connections. In this way, if E is a vector bundle on Z, the cohomology \(H^ r(Z,{\mathcal O}(E))\) obtained through the spectral sequence can be interpreted as the kernel of a differential operator on X. This formulation allows a far-reaching generalisation of the Penrose and Ward transforms arising in mathematical physics.
The second part of the paper contains an explicit realisation of this program for several particular cases, mostly from twistor theory. In these examples, Y is a flag manifold. These interesting calculations are most welcome. As the author states, there should be many other uses of these ideas.
