Abstract
Quantum-classical equations of motion satisfying Jacobi identity were recently proposed by V. V. Kisil (Europhys. Lett., 72 (2005) 873), generalizing the Heisenberg group formulation of quantum mechanics. In the attempt to provide a physical interpretation for the resulting quantum-classical dynamics, we have reconstructed and analyzed the derivation, finding that there is a suitable representation from which the purely classical nature of the supposedly quantum-classical equations of motion clearly emerges.
