Finite-gap potentials and integrable geodesic equations on a 2-surface
Abstract
In this paper we show that the one-dimensional Schr\"odinger equation can be viewed as the geodesic equation of a certain metric on a 2-surface. In case of the Schr\"odinger equation with a finite-gap potential, the metric and geodesics are explicitly found in terms of the Baker--Akhiezer function
