An Example of Poincare Symmetry with a Central Charge
arXiv:hep-th/9810242 · doi:10.1016/S0370-2693(98)01510-X
Abstract
We discuss a simple system which has a central charge in its Poincare algebra. We show that this system is exactly solvable after quantization and that the algebra holds without anomalies.
