Query: The Representation of Quantum Field Theory without Infinity Bare Masses
  and Coupling Constants of Fermions   The paper presents the representation of quantum field theory without
introduction of infinity bare masses and coupling constants of fermions.
Counter-terms, compensating for divergent quantities in self-energy diagrams of
fermions and vacuum polarization diagrams at all orders of the perturbation
theory, appear in the appropriate Hamiltonians under the special time-dependent
unitary transformation.
