FIFTY YEARS OF EIGENVALUE PERTURBATION

In many cases where eigenvalue perturbation theory cannot be shown to converge or can even be shown to diverge (e.g. the anharmonic oscillator, example 2; see below), the series still makes sense term by term. It is natural to try to associate these formal series with an asymptotic series in a class ...
