Reduction and Unfolding for Quantum Systems: the Hydrogen Atom
A. D'Avanzo, G. Marmo, A. Valentino
In this paper we propose a ``quantum reduction procedure'' based on the reduction of algebras of differential operators on a manifold. We use these techniques to show, in a systema…

Reduction and unfolding: the Kepler problem
Antonella D'Avanzo, Giuseppe Marmo
In this paper we show, in a systematic way, how to relate the Kepler problem to the isotropic harmonic oscillator. Unlike previous approaches, our constructions are carried over in…
