DUAL PERTURBATION EXPANSION FOR A CLASSICAL λϕ4 FIELD THEORY
Abstract
We prove the existence of a strong coupling expansion for a classical λϕ4 field theory in agreement with the duality principle in perturbation theory put forward in a paper: M. Frasca, Phys. Rev. A58, 3439 (1998). The leading order solution is a snoidal wave taking the place of plane waves of the free theory. We compute the first-order correction and show that higher-order terms do renormalize the leading order solution.
