Weigel reports about his development of an efficient method, based on scattering data (spectral method) about a scalar field configuration of given topology (static solution to the classical equation of motion), to compute its one-loop effective potential (or vacuum polarization energy, VPE) in a 1 + 1D [[phi].sup.6] (nonrenormalizable) theory where fluctuations do not naturally decompose into parity eigenstates since the background field may connect inequivalent vacua (not related by a parity transformation).
The G-parity transformation is analogous to ordinary parity transformation in configurational space, which inverts the direction of three vectors.
