Abstract
Minimal equations for Green's functions for systems of spinor and (pseudo) scalar fields with derivative coupling are compared with those for systems with nonderivative couplings, and it is found that there remain terms with explicit coupling constant. For systems containing vector (or axial-vector) fields, one cannot derive Ward-Takahashi identities. Alternative choices (gauges) of two-point and three-point functions are discussed.
