Phys. Rev. Lett. 42, 547–548 (1979)Proof of the Positive-Action Conjecture in Quantum RelativityReceived 27 November 1978; published in the issue dated 26 February 1979 We extend our previous method of proving the positive-mass conjecture to prove the positive-action conjecture of Hawking for asymptotically Euclidean metric. This result is crucial in proving the path integral convergent in the Euclidean quantum gravity theory. © 1979 The American Physical Society URL:
