Q-EXACT ACTIONS FOR BF THEORIES

The actions for all classical (and consequently quantum) BF theories o n n-manifolds is proven to be given by anti-commutators of hermitian, nilpotent, scalar fermionic charges with Grassmann-odd functionals. In order to show this, the space of fields in the theory must be enlarge d to include ''mass terms'' for new, non-dynamical, Grassmann-odd fiel ds. The implications of this result on observables are examined.
