6 Dec 2002 | Journal: | Class.Quant.Grav. 20 (2003) S487-S493 | Subject: | hep-th | Abstract: | In the present talk I shall review the construction of N=2 supergravity models exhibiting stable de Sitter vacua. These solutions represent the first instance of stable backgrounds with positive cosmological constant in the framework of extended supergravities (N >=2). After briefly reviewing the role of de Sitter space--times in inflationary cosmology, I shall describe the main ingredients which were necessary for the construction of gauged N=2 supergravity models admitting stable solutions of this kind. | Source: | arXiv, hep-th/0301024 | Services: | Forum | Review | PDF | Favorites |
