Phys. Rev. D 53, 5966–5969 (1996)Barbero's Hamiltonian derived from a generalized Hilbert-Palatini actionReceived 27 November 1995; published in the issue dated 15 May 1996 Barbero recently suggested a modification of Ashtekar's choice of canonical variables for general relativity. Although leading to a more complicated Hamiltonian constraint this modified version, in which the configuration variable still is a connection, has the advantage of being real. In this article we derive Barbero's Hamiltonian formulation from an action, which can be considered as a generalization of the ordinary Hilbert-Palatini action. © 1996 The American Physical Society URL:
