Query: Convergent sequences of perturbative approximations for the anharmonic
  oscillator II. Compact time approach   We present an alternative pathway in the application of the variation
improvement of ordinary perturbation theory exposed in [1] which can preserve
the internal symmetries of a model by means of a time compactification.
