| Abstract: | Quantizations are considered as mappings from the algebra of classical polynomial observables into the algebra of quantum polynomial observables satisfying a minimal set of natural requirements. Physically important subclasses of quantizations are specified by further symmetry assumptions.In the second part quantizations are defined as deformations of the classical algebra of polynomial observables. The relation of these deformations to the quantization mappings is clarified.Dedicated to Academician Václav Votruba on the occasion of his seventieth birthday. |
