Maximum radius of convergence perturbation theory

The Journal of Chemical Physics, 2000
An ab initio method is introduced, called the maximum radius of convergence (MAXRc) perturbation theory, that exploits the added degrees of freedom permitted with flexible energy denominator perturbation theory [J. Chem. Phys. 109, 7725 (1998)] by defining the energy-denominator factors of a Rayleigh–Schrödinger perturbative expansion to be ...

The Validity of Perturbation Series with Zero Radius of Convergence

Journal of Mathematical Physics, 1966
Although the perturbation expansion for the S-matrix of the Peres-model field theory has zero radius of convergence, it uniquely defines the S-matrix and is easily summable by the method of Padé approximants.
