Phys. Rev. D 59, 047505 (1999) [4 pages]Yang-Mills analogues of the Immirzi ambiguityReceived 3 September 1998; published 28 January 1999 We show that the somewhat controversial “Immirzi ambiguity” of the Ashtekar-like formulation of canonical quantum gravity has strong similarities with other ambiguities that appear in Yang-Mills theories, such as the θ ambiguity. This clarifies the role of the ambiguities. We also discuss other ambiguities in the Maxwell case, and the implications for the loop quantization of these theories. © 1999 The American Physical Society URL:
