摘要
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 a 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. [S0556-2821(99)01004-8].
