Description

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
