Penrose transform and monogenic functions
  Penrose transform tells us that there is an isomorphism of the kernel of an invariant differential operator studied in the paper [TS] and sheaf cohomology of some vector bundle on twistor space. The point of this paper is to write down this isomorphism explicitly. Explicit form of the isomorphism will be crucial for further investigation on the properties of the complex.
