3. Heavy (bold) lines are used for denoting exact Green's functions, light lines standing for nonperturbed Green's functions. Using bold lines while introducing appropriate constraints on the diagram structure (to prevent double counting) accounts for partial summation of diagrams. [See, e.g., A.L. Fetter and J.D. Walecka, Quantum Theory of Many-Particle Systems (Dover, New York, 2003).]
