Abstract: (desy)
For a large class of gauge theories a nilpotent BRS-operator is constructed and its cohomology in the space of local functionals of the off-shell fields is shown to be isomorphic to the cohomology of \4s=s+d on functions f(\4C,\PH) of tensor fields \PH and of variables \4C which are constructed of the ghosts and the connection forms. The result allows general statements about the structure of invariant classical actions and anomaly candidates whose BRS-variation vanishes off-shell. The assumptions under which the result holds are thoroughly discussed.- transformation: Becchi-Rouet-Stora
