One formulation for both lineal gravities through a dimensional reduction
The two lineal gravities - based on the de Sitter group or a central extension of the Poincaré group in 1 + 1 dimension - are shown to derive classically from a unique topological gauge theory. This one is obtained after a dimensional reduction of a Chern-Simons model, which describes pure gravity i...

Summary: | The two lineal gravities - based on the de Sitter group or a central extension of the Poincaré group in 1 + 1 dimension - are shown to derive classically from a unique topological gauge theory. This one is obtained after a dimensional reduction of a Chern-Simons model, which describes pure gravity in 2 + 1 dimensions, the gauge symmetry being given by an extention if ISO (2, 1). |
