Chaplygin gas with field-dependent Poincare symmetry
arXiv:hep-th/0101044
Abstract
The relativistic generalization of the Chaplygin gas, put forward by Jackiw and Polychronakos, is derived in Duval's Kaluza-Klein framework, using a universal quadratic Lagrangian. Our framework yields a simplified proof of the field-dependent Poincaré symmetry Our action is related to the usual Nambu-Goto action [world volume] of -branes in the same way as the Polyakov and the Nambu action are in strings theory.
