Wissenschaft und Verantwortung,tures on an even-dimensional Riemannian manifold ., has generated much interest. Generalized twistor theory is playing an increasing role in the study of conformai properties of Riemannian manifolds and in many other topics, such as the classification of harmonic maps into homogeneous spaces (cf., e

Wissenschaft und Verantwortung,We have not attempted to make an exhaustive compilation of the existing literature on the subject, nor to present a complete account of the state-of-the-art. Instead, we have tried to present a coherent unifying frame for the most basic results of the theory, based in part on our earlier works [7–10

Attention to such objects was first drawn by the study of the tangential Cauchy-Riemann complex, as in Andreotti and Hill by the use of a Mayer-Vietoris sequence relating the cohomology of this complex to that of
