| 摘要： We start with a review of the basic setting of Covariant Quantum Mechanics in a curved spacetime equipped with absolute time and a riemannian spacelike metric. Then, we discuss the Lie algebras of in nitesimal symmetries of the main co-variant geometric objects of covariant quantum mechanics: the time form, the her-mitian metric, the upper quantum connection, the quantum lagrangian. Indeed,these in nitesimal symmetries are generated, in a covariant way, by the Lie algebra of time preserving conserved special phase functions. Actually, this Lie algebra of special phase functions generates also the Lie algebra of in nitesimal symmetries of the main classical objects: the time form and the cosymplectic 2-form. A natural output of the classi cation of the quantum symmetries is a covariant approach to quantum operators. Further, we discuss the classical and quantum currents associated with special phase functions. Actually, the well known probability current turns out to be a very particular case of the above approach to quantum currents. |
