Abstract
We analyze the recently proposed definition of the off-shell, gauge-invariant, gauge-independent, effective action Γ , utilizing an invariant metric on the field space. It is shown how to establish correspondence between Γ and the standard effective action, calculated in some particular (Landau-type) gauge. Several examples are explicitly discussed, including Yang-Mills theory, the effective potential in scalar QED, and one-loop quantum gravity. Generalization to the case of super-invariant theories (e.g. super-Yang-Mills and supergravity) is also presented.
