Variational perturbation theory in φ4-model

  • 1. Joint Inst. for Nuclear Research, Dubna (Russian Federation)

Description

A nonperturbation method is dwelled on in quantum field theory - the variational perturbation theory (VPT). This method combines the variational principle and calculation of the corrections to the leading contribution and uses the functional integration as a mathematical tool. The given method is formulated in terms of the Gaussian functional quadratures (like in perturbation theory). The VPT method is applied to the Green function of the φ4-model in Euclidean d-dimensional space. 19 refs
