Let 1W, g) be a spin manifold of dimension n. In terms of the Dirac operator P of (W, g), we introduce on the spinor fields a conformally covariant first-order operator D that is strictly connected with the twisror-spinors. We show that the operator (L~-p) (p (n/4(n .-1))R) is positive. For a compac

## Abstract On a spin Kähler manifold __M^2m^__ a new first integral __Q__~Ψ~ of the Kählerian twistor equations is presented. If the scalar curvature has a critical point then __Q__~Ψ~ vanishes. In case __M^2m^__ is closed, this fact provides a simple geometrical obstruction for Kählerian twistor
A relationship between N = 2 supersymmetric Yang-Mills instantons on the Euclidean four space and certain holomorphic super vector bundles over super twistor space is investigated. We give the ADHM-matrix solutions of N = 2 supersymmetric instantons.
