Voros, André Problème spectral de Sturm-Liouville: Le cas de l’oscillateur quartique. (French) Zbl 0534.70014 Sémin. Bourbaki, 35e année, 1982/83, Exp. 602, Astérisque 105-106, 95-104 (1983). Methods are proposed for studying the spectrum of the stationary Schrödinger equation [-\(\hslash \!-^ 2d^ 2/dq^ 2+(V(q)- E)]\Psi(q)=0\), where V(q) is a quartic polynomial. From the text: ”la méthode semi-classique exacte... a déjà pu produire des résultats inattendus, mais il reste encore beaucoup à faire pour expliciter davantage ses possibilités...”.For the entire collection see [Zbl 0514.00009].
