Query: The inverse Penrose transform on Riemannian twistor spaces   With respect to the Dirac operator and the conformally invariant Laplacian,
an explicit description of the inverse Penrose transform on Riemannian twistor
spaces is given. A Dolbeault representative of cohomology on the twistor space
is constructed from a solution of the field equation on the base manifold.
