Green Function Method for Nonlinear Systems
arXiv:hep-th/0702056 · doi:10.1142/S0217732307023705
Abstract
We show that a Green function solution can be given for a class of non-homogeneous nonlinear systems having relevance in quantum field theory. This in turn means that a quantum field theory in the strong coupling limit can be formulated and the spectrum obtained.
