Extended de Sitter Theory of Two Dimensional Gravitational Forces
arXiv:hep-th/9308021 · doi:10.1103/PhysRevD.48.5721
Abstract
We present a simple unifying gauge theoretical formulation of gravitational theories in two dimensional spacetime. This formulation includes the effects of a novel matter-gravity coupling which leads to an extended de Sitter symmetry algebra on which the gauge theory is based. Contractions of this theory encompass previously studied cases.
