Symmetries in tetrad theories
Abstract
The isometry conditions for gravitational fields are given directly at the tetrad level, rather than in terms of the metric. As an illustration, an analysis of the curvature collineations and Killing fields for a twisting typeN vacuum gravitational field is made.
