Phys. Rev. D 38, 490–497 (1988)Spin-two fields, general covariance, and conformal invarianceReceived 19 November 1987; published in the issue dated 15 July 1988 A method to determine the most general type of gauge invariance for a massless spin-two field has recently been formulated. It was shown that a consistent nonlinear generalization of the linearized Einstein equations yields theories that are either ‘‘normal’’ spin-two gauge invariant or generally covariant. In this paper this analysis is extended to include conformally invariant theories. © 1988 The American Physical Society URL:
