本文讨论了从扭量代数发展而来的局部扭量的形式，并将扭量的一些基本概念推广到弯曲时空。基本上，中心思想是在时空的每一点定义一个扭量空间，并定义一个协变导数，这样局部扭量输运的操作是可能的;这导致共形不变曲率扭量的定义。在附录中讨论了一些共形不变旋量。
This paper deals with the formalism of local twistors, which has developed from the twistor algebra, and extends some of the basic twistor concepts to curved space-time. Essentially, the central ideas are to define a twistor space at each point of the spacetime, and to define a covariant derivative so that an operation of local twistor transport is possible; this leads to the definition of a conformally invariant curvature twistor. In an appendix, some conformally invariant spinors are discussed.
