    From the point of view of an associated effective Lagrangian in space-time one may look askance at the quantities\((p\psi \cdot p\psi )^{ - 1} \) and\((p\gamma \cdot p\psi )^{ - 1} \), since, in such an effective Lagrangian, these quantities correspond to nonlocal (integral) operators.Google Scholar
