geometric quantization
[ˌdʒi:əˈmetrɪk ˌkwɔntaiˈzeiʃən]
In mathematical physics, geometric quantization is a mathematical approach to defining a quantum theory corresponding to a given classical theory. It attempts to carry out quantization, for which there is in general no exact recipe, in such a way that certain analogies between the classical theory and the quantum theory remain manifest.
