From useful algorithms for slowly convergent series to physical predictions based on divergent perturbative expansions
This review is focused on the borderline region of theoretical physics and mathematics. First,
we describe numerical methods for the acceleration of the convergence of series. These …

Coupled anharmonic oscillators. I. Equal-mass case
T Banks, CM Bender, TT Wu - Physical Review D, 1973 - APS
This is the first in a series of papers on the large-order behavior of perturbation theory for
coupled anharmonic oscillators. We exploit previously published dispersion techniques to …

Semiclassical analysis of low lying eigenvalues, II. Tunneling
B Simon - Annals of Mathematics, 1984 - JSTOR
We discuss the leading asymptotics of eigenvalue splittings of-1/2 Δ+ λ2V in the limit as
λ→∞, and where V is a non-negative potential with several zeros. For example, if E0 (λ), E1 …
