WebbProf. Heckman gives in his lecture notes (in Dutch) a quantum mechani-cal/group theoretical treatment of the Kepler problem. He mentions with-out proof a few properties of the Laplace-Runge-Lenz-Pauli vector, which are used in his subsequent development. In these notes these properties are formulated in Theorem 2 and proved. WebbIn classical mechanics, the Laplace – Runge – Lentz vector is a vector that is mainly used to describe the shape and orientation of the orbit in which one celestial body revolves around another (for example, the orbit in which the planet rotates around a star).
