# Classical Systems in Quantum Mechanics

@article{Bona2019ClassicalSI, title={Classical Systems in Quantum Mechanics}, author={Pavel B'ona}, journal={arXiv: Mathematical Physics}, year={2019} }

If we admit that quantum mechanics (QM) is universal theory, then QM should contain also some description of classical mechanical systems. The presented text contains description of two different ways how the mathematical description of kinematics and dynamics of classical systems emerges from the mathematical formalism of QM. The first of these ways is to obtain an equivalent description of QM (with finite number of degrees of freedom) as a classical Hamiltonian field theory and afterwards…
