    "abstract": "Recently-developed variational perturbation expansions converge exponentially\nfast for positive coupling constants. They do not, however, possess the correct\nleft-hand cut in the complex coupling constant plane, implying a wrong\nlarge-order behavior of their Taylor expansion coefficients. We correct this\ndeficiency and present a method of resumming divergent series with their proper\nlarge-order behavior. For a given set of expansion coefficients, knowledge of\nthe large-order behavior considerably improves the quality of the\napproximation.",
