Gauge Invariant Formulations of Lineal Gravity

arXiv:hep-th/9203056 · doi:10.1103/PhysRevLett.69.233

Abstract

It is shown that the currently studied ``string-inspired'' model for gravity on a line can be formulated as a gauge invariant theory based on the Poincaré group with central extension -- a formulation that complements and simplifies H.~Verlinde's construction based on the unextended Poincaré group.
