AdS and stabilized extra dimensions in multidimensional gravitational models with nonlinear scalar curvature terms 1/R and R^4
Uwe Guenther, Alexander Zhuk, Valdir Bezerra +1
We study multidimensional gravitational models with scalar curvature nonlinearities of the type 1/R and R^4. It is assumed that the corresponding higher dimensional spacetime manif…
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…
Perfect fluid brane-world model
M. Bouhmadi-Lopez, P. F. Gonzalez-Diaz, A. Zhuk
By considering 5--dimensional cosmological models with a bulk filled with a perfect fluid and a cosmological constant, we have found regular instantonic solution which is free from…
