Broken sigma-model isometries in very special geometry | | Bernard de Wit

28 Jul 1992 | | Journal: | Phys.Lett. B293 (1992) 94-99 | | Subject: | hep-th | | Abstract: | We show that the isometries of the manifold of scalars in $N=2$ supergravity in $d=5$ space-time dimensions can be broken by the supergravity interactions. The opposite conclusion holds for the dimensionally reduced $d=4$ theories, where the isometries of the scalar manifold are always symmetries of the full theory. These spaces, which form a subclass of the {em special} Kähler manifolds, are relevant for superstring compactifications. | | Source: | arXiv, hep-th/9207091 | | Services: | Forum | Review | PDF | Favorites | |
