Gauss - Bonnet brane cosmology
We consider 5-dimensional spacetimes of constant 3-dimensional spatial curvature in the presence of a bulk cosmological constant. We find the general solution of such a configuration in the presence of a Gauss-Bonnet term. Two classes of non-trivial bulk solutions are found. The first class is valid only under a fine tuning relation between the Gauss-Bonnet coupling constant and the cosmologica...
متن کاملLagrange Multipliers for Higher Order Elliptic Operators
In this paper, the Babuška’s theory of Lagrange multipliers is extended to higher order elliptic Dirichlet problems. The resulting variational formulation provides an efficient numerical squeme in meshless methods for the approximation of elliptic problems with essential boundary conditions. Mathematics Subject Classification. 41A10, 41A17, 65N15, 65N30. Received: April 5, 2004.

متن کاملNoether symmetries in Gauss–Bonnet-teleparallel cosmology
A generalized teleparallel cosmological model, [Formula: see text], containing the torsion scalar T and the teleparallel counterpart of the Gauss-Bonnet topological invariant [Formula: see text], is studied in the framework of the Noether symmetry approach. As [Formula: see text] gravity, where [Formula: see text] is the Gauss-Bonnet topological invariant and R is the Ricci curvature scalar, ex...
متن کاملGauss-Bonnet Brane Cosmology with Radion Stabilization
G.L. Alberghi 2, 3, ∗ and A. Tronconi 3, † Department of Physics, University of Bologna, Via Irnerio 46, 40126 Bologna, Italy. Department of Astronomy, University of Bologna, Italy. I.N.F.N., Sezione di Bologna, Italy. We study cosmology in a five-dimensional brane-world with a stabilizing effective potential for the radion and matter localized on the two branes. We consider the corrections ind...
