Szenthe, J. (ed.) et al., Differential geometry and its applications. Proceedings of a colloquium, held in Eger, Hungary, August 20-25, 1989, organized by the János Bolyai Mathematical Society. Amsterdam: North- Holland Publishing Company. Colloq. Math. Soc. János Bolyai. 56, 629-636 (1992).
The author extends the results from J. Marsden, R. Montgomery and T. Raţiu [Reduction, symmetry and Berry’s phase in mechanics (to appear)] concerning the reconstruction of the dynamics on the phase space \(M\) with a symmetry group from that of the reduced phase space, at the prequantic level. The main result is
Theorem 4.1. Let \(H\) be a \(G\)-invariant smooth function on \(T^*M\) and \(H_ \mu\) its restriction to \((T^*M)_ \mu\). Then the prequantum operator \(Q_ H\) on the extended phase space \(T^*M\) can be determined from the prequantum operator \(Q_{H_ \mu}\) on the reduced phase space \((T^*M)_ \mu\) via the connection 1-form \(\alpha^ \mu\), \(\widetilde\gamma\) and \(\gamma\).
