Abstract Introduction of a BRST-gauge-fixing regulator to make the inner product on the physical subspace well-defined. Application of this formalism to Yang-Mills theories, gravity in Ashtekar's variables, and 2+1 dimensional gravity. Study of the relation between the loop formalism and the gauge regularization.
