Variational perturbation theory
text:
In mathematics, variational perturbation theory (VPT) is a mathematical method to convert divergent power series in a small expansion parameter, say into a convergent series in powers where ω is a critical exponent. This is possible with the help of variational parameters, which are determined by optimization order by order in g . The partial sums are converted to convergent partial sums by a method developed in 1992. Most perturbation expansions in quantum mechanics are divergent for any small
