Bogomolny's semiclassical transfer operator for rotationally invariant integrable systems

The transfer operator due to Bogomolny provides a convenient method for obtaining a semiclassical approximation to the energy eigenvalues of a quantum system, no matter what the nature of the analogous classical system. In this paper, the method is applied to integrable systems which are rotationally invariant, in two and three dimensions. In two dimensions, the transfer operator is expanded in a Fourier series in the angle variable, while in …
