The spectrum is derived from the topological invariants of a particular principal fiber bundle which can be assigned to any configuration of classical mechanics, when formulated according to Maupertuis formalism.Prepared for Proceedings of GP26Mathematical PhysicsGeneral Relativity and Quantum Cosmologytext
