Abstract

We present some examples of mechanical systems such that given n constants of motion in involution (where n is the number of degrees of freedom), we can identify a coordinate system in which the Hamilton-Jacobi equation is separable (or R-separable), with the separation constants being the values of the given constants of motion. Analogous results for the Schrödinger equation are also given.

Keywords: Hamilton-Jacobi equation; constants of motion; separation of variables; R-separability; Schrödinger equation.

 

Resumen

Presentamos algunos ejemplos de sistemas mecánicos tales que dadas n constantes de movimiento en involución (donde n es el número de grados de libertad), podemos identificar un sistema de coordenadas en el cual la ecuación de Hamilton-Jacobi es separable (o R-separable), con las constantes de separación siendo los valores de las constantes de movimiento dadas. Se dan resultados análogos para la ecuación de Schrödinger.

Descriptores: Ecuación de Hamilton-Jacobi; constantes de movimiento; separación de variables; R-separabilidad; ecuación de Schrödinger.
