On the harmonic oscillator on the Lobachevsky plane

Abstract

We introduce the harmonic oscillator on the Lobachevsky plane with the aid of the potential $V(r)=(a^2{\omega }^2/4)sinh(r/a{)}^2$ where $a$ is the curvature radius and $r$ is the geodesic distance from a fixed center. Thus the potential is rotationally symmetric and unbounded likewise as in the Euclidean case. The eigenvalue equation leads to the differential equation of spheroidal functions. We provide a basic numerical analysis of eigenvalues and eigenfunctions in the case when the value of the angular momentum, $m$, equals 0.
