Classical limit of a relativistic quantum system (Q798936)

The Poincaré covariant Hamiltonian particle dynamics proposed by Aaberge is formulated in terms of a \(W^*\)-algebra in a standard representation, both for the classical and the quantum case. This formulation provides a unified description mode of both classical and quantum mechanics. The classical kinematics is then obtained as the \(\hslash\to 0\) limit of the corresponding quantum operator algebra.
