Overcoming Nonrenormalizability
Abstract
Description
A suitable counterterm for a Euclidean space lattice version of ϕ^4_n theories, n\ge 4, is combined with several additional procedures so that in the continuum limit the resultant quantum field theory is nontrivial. Arguments to support this unconventional choice are presented.
