On Conformal Invariants Built from Spinor Fields

Abstract

By means of a conformal covariant differentiation process we construct generating systems for conformally invariant symmetric (r, s) -spinors in an arbitrary curved space -time. Extending this method to conformally invariant linear differential operators acting on symmetric spinor fields some classes of such operators are derived. 0.1991 Mathematics Subject Classification. 53A30, 53A50, 83C60.
