CONVERGENCE OF AN EXACT QUANTIZATION SCHEME ARTUR AVILA
 

Summary: CONVERGENCE OF AN EXACT QUANTIZATION SCHEME
ARTUR AVILA
Abstract. It has been shown by Voros [V1] that the spectrum of the one-dimensional homo-
geneous anharmonic oscillator (Schr¨odinger operator with potential q2M , M > 1) is a fixed
point of an explicit non-linear transformation. We show that this fixed point is globally and
exponentially attractive in spaces of properly normalized sequences.
1. Introduction
Let 0 < < be a constant. For E, E > 0, define
(1.1) (E , E) = tan-1 sin
E E-1 + cos

Let X = (Xk)
k=1, Y = (Yj )
j=1 be sequences of positive real numbers and define = (j )
