Phys. Rev. D 14, 2505–2510 (1976)Canonical vierbein form of general relativityReceived 17 February 1976; published in the issue dated 15 November 1976 The Einstein action is expressed in canonical form using the vierbein fields as basic variables. In addition to general covariance, it exhibits the local Lorentz invariance associated with the freedom of choice of the orthonormal frames. © 1976 The American Physical Society URL:
