    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. © 2005 Elsevier B.V. All rights reserved.
