Two-parameter convergent perturbation theory for quantum anharmonic oscillator
Description
A convergent two-parameter perturbation theory is constructed for the ground state energy of anharmonic quantum oscillator. Values of the parameters are found for which the convergence rate of the series has its maximum. A method is proposed for calculation of the asymptotics of higher terms in the series which is not based on the steepest descent
