One Formulation for both Lineal Gravities through a Dimensional Reduction | | Daniel Cangemi
; | | Date: |
23 Jul 1992 | | Journal: | Phys.Lett. B297 (1992) 261 | | Subject: | gr-qc hep-th | | Abstract: | The two lineal gravities --- based on the de Sitter group or a central extension of the Poincaré group in 1+1 dimensions --- 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 extension of ISO(2,1). | | Source: | arXiv, gr-qc/9207004 | | Services: | Forum | Review | PDF | Favorites | |
