Abstract
This paper develops a formalism for the generating functionals for partial distribution functions in classical statistical mechanics and partial density matrices in quantum statistical mechanics. For the case of a large canonical ensemble, functional equations are written with respect to the functionals introduced. Each functional system creates a system of integral equations for distribution functions or density matrices.
