Noncentral extensions as anomalies in classical dynamical systems
A two cocycle is associated to any action of a Lie group on a symplectic manifold. This allows to enlarge the concept of anomaly in classical dynamical systems considered by F Toppan in [<i>J. Nonlinear Math. Phys.</i> 8, Nr. 3 (2001), 518–533] so as to encompass some extensions of Lie a...

| Sumario: | A two cocycle is associated to any action of a Lie group on a symplectic manifold. This allows to enlarge the concept of anomaly in classical dynamical systems considered by F Toppan in [<i>J. Nonlinear Math. Phys.</i> 8, Nr. 3 (2001), 518–533] so as to encompass some extensions of Lie algebras related to noncanonical actions. |
