Phys. Rev. D 41, 1105–1111 (1990)Complex action and quantum gravityReceived 2 October 1989; published in the issue dated 15 February 1990 We give a general framework of quantum mechanics for the system of Lagrangians containing complex total-derivative terms. After being examined for the harmonic oscillator, our formalism is applied to Einstein gravity. It leads to a systematic quantum theory of Ashtekar's new canonical gravity. © 1990 The American Physical Society URL:
