Abstract
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.Keywords
