Stats
(1) Definition of Green Functions: Green functions, denoted as ⌧8 9 (C, C0)
(2) Calculation Process: Loop expansion involves expanding Green functions in terms of perturbation terms.
(3) Analysis: Lower-order loops represent direct interactions, while higher-order loops indicate complex interactions.
