Abstract: | Green's function equations are considered for interacting spinor and (pseudo) scalar fields with interactions
. These equations do not determine higher many-point functions if two-point functions are given as “input.” If vertex parts
are given as input, two-point functions are determined but higher many-point functions are not determined. |
