Stabilization of Compactification Radius by Bulk and Brane Ghost Yang-Mills Gauge Fields
P. Castelo Ferreira, P. Vargas Moniz
This paper has been withdrawn by the authors. It contains several errors that the authors believe can still be corrected. However one of the authors strongly disagrees with the set…
Nonlinear multidimensional cosmological models with form fields: stabilization of extra dimensions and the cosmological constant problem
U. Guenther, P. Moniz, A. Zhuk
We consider multidimensional gravitational models with a nonlinear scalar curvature term and form fields in the action functional. In our scenario it is assumed that the higher dim…
Multidimensional cosmology and asymptotical AdS
U. Guenther, P. Moniz, A. Zhuk
A non-linear gravitational model with a multidimensional geometry and quadratic scalar curvature is considered. For certain parameter ranges, the extra dimensions are stabilized if…
FRW Cosmological Solutions in M-theory
Marco Cavaglia, Paulo Vargas Moniz
We present the canonical and quantum cosmological investigation of a four-dimensional, spatially flat, Friedmann-Robertson-Walker (FRW) model that is derived from the bosonic Neveu…
Can we obtain Conserved Currents in Supersymmetric Quantum Cosmology?
P. V. Moniz
In this paper we report whether conserved currents can be sensibly defined in supersymmetric minisuperspaces. Our analysis deals with a k=1 FRW model. Supermatter in the form of sc…
Quantum Analysis of the Compactification Process in the Multidimensional Einstein-Yang-Mills System
O. Bertolami, P. D. Fonseca, P. V. Moniz
We study solutions of the Wheeler-DeWitt equation obtained when considering homogeneous and isotropic (up to a gauge transformation) field configurations of the Einstein-Yang-Mills…
