Local Approximation in Renormalizable and Nonrenormalizable Theories. I
Korkut Bardakci, Bert Schroer · Journal of Mathematical Physics · 1966
We present a framework of quantum field theory which is wide enough to incorporate renormalizable, as well as nonrenormalizable theories. A universal high-energy bound for matrix elements of fields is derived. The ``string'' approximation of the two-point function for various couplings is studied.
