Multi-(super)graviton theory on topologically non-trivial backgrounds
arXiv:hep-th/0506082 · doi:10.1016/j.physletb.2005.07.061
Abstract
It is shown that in some multi-supergraviton models, the contributions to the effective potential due to a non-trivial topology can be positive, giving rise in this way to a positive cosmological constant, as demanded by cosmological observations.
