29 Apr 2003 | Journal: | JHEP 0401 (2004) 007 | Subject: | hep-th | Abstract: | We construct consistent non-linear Kaluza Klein reduction ansatze for a subset of fields arising from the reduction of IIB* and M* theory on dS_5 x H^5 and dS_4 x AdS_7, respectively. These reductions yield four and five-dimensional de Sitter supergravities, albeit with wrong sign kinetic terms. We also demonstrate that the ansatze may be used to lift multi-centered de Sitter black hole solutions to ten and eleven dimensions. The lifted dS_5 black holes correspond to rotating E4-branes of IIB* theory. | Source: | arXiv, hep-th/0304253 | Services: | Forum | Review | PDF | Favorites |
