M ar 2 00 9 Cosmological scaling solutions in generalised Gauss - Bonnet gravity theories
The conditions for the existence and stability of cosmological power-law scaling solutions are established when the Einstein-Hilbert action is modified by the inclusion of a function of the Gauss-Bonnet curvature invariant. The general form of the action that leads to such solutions is determined for the case where the universe is sourced by a barotropic perfect fluid. It is shown by employing ...
متن کاملThe instability of vacua in Gauss-Bonnet gravity
Owing to the quadratic nature of the theory, Einstein-Gauss-Bonnet gravity generically permits two distinct vacuum solutions. One solution (the ”Einstein” vacuum) has a well defined limit as the Gauss-Bonnet coupling goes to zero, whereas the other solution (the ”stringy” vacuum) does not. There has been some debate regarding the stability of these vacua, most recently from Deser & Tekin who ha...
متن کاملScalar-Tensor Gravity on a Gauss-Bonnet Brane World
The effective four-dimensional, linearised gravity for a brane world model with higher order curvature terms and a bulk scalar field is analysed. Large and small distance gravitational laws are derived. The model has a single brane embedded in a fivedimensional bulk spacetime, and the scalar field represents the dilaton or a moduli field. The quadratic, Gauss-Bonnet curvature term (and correspo...
متن کاملGauss-Bonnet Brane World Gravity with a Scalar Field
The effective four-dimensional, linearised gravity of a brane world model with one extra dimension and a single brane is analysed [1, 2]. The model includes higher order curvature terms (such as the Gauss-Bonnet term) and a conformally coupled scalar field. Large and small distance gravitational laws are derived. In contrast to the corresponding Einstein gravity models, it is possible to obtain...
متن کاملModified teleparallel theories of gravity: Gauss–Bonnet and trace extensions
We investigate modified theories of gravity in the context of teleparallel geometries with possible Gauss-Bonnet contributions. The possible coupling of gravity with the trace of the energy-momentum tensor is also taken into account. This is motivated by the various different theories formulated in the teleparallel approach and the metric approach without discussing the exact relationship betwe...
