Several composite field product expansion in the regime when each coordinate set approaches its center

Several composite field product expansion in the regime when each coordinate set approaches its center is derived for arbitrary mass theory with dimensionless binding constants. Expansion is carried out in frames of renormalized Bogolyubov-Parasyuk procedure. Coefficient functions of expansion are explicitly represented in terms of some Green functions. It is marked that expansion is easily generalized for other renormalization diagrams and larger coordinate sets. 6 refs
