The integration of G-invariant functions and the geometry of the Faddeev- Popov procedure
Various versions of the Fubini theorem on the principal fibre bundle are derived. The formal generalizations of these theorems are used as a basic tool for the investigation of the geometrical setting of the Faddeev- Popov procedure in the cases of pure Yang-Mills theories, spinless particle and Polyakov's bosonic string.
