T-Duality and Spinning Solutions in 2 + 1 Gravity | Chiang-Mei Chen
; | Date: |
30 Oct 1998 | Journal: | Nucl.Phys. B544 (1999) 775-788 | Subject: | hep-th | Abstract: | Starting with the 2+1 Einstein--Maxwell--Dilaton system with a cosmological constant and assuming two commuting Killing symmetries we derive the corresponding $1+0 sigma$--model. It is shown that, for general values of the coupling parameters, the $T$--duality group is $SL(2,R)$, which coincides with the group of linear coordinate transformations along the Killing orbits. This duality, along with a suitable parameter choice, is applied to obtain some new spinning solutions in the alternative gravity theories: Einstein--Maxwell, Brans--Dicke and Einstein--Maxwell--Dilaton. | Source: | arXiv, hep-th/9810245 | Services: | Forum | Review | PDF | Favorites |
