Noether symmetry for Gauss-Bonnet dilatonic gravity
Noether symmetry Gauss-Bonnet dilatonic
2011/9/27
Noether symmetry for Gauss-Bonnet-Dilatonic interaction exists for a constant dilatonic scalar potential and a linear functional dependence of the coupling parameter on the scalar field. The symmetry ...
Vainshtein mechanism in Gauss-Bonnet gravity and Galileon aether
Vainshtein mechanism Gauss-Bonnet gravity Galileon aether
2011/10/18
We derive field equations of Gauss-Bonnet gravity in 4 dimensions after dimensional reduction of the action and demonstrate that in this scenario Vainshtein mechanism operates in the flat spherically ...
Slow-roll inflation with a Gauss-Bonnet correction
Slow-roll inflation Gauss-Bonnet correction
2010/3/19
We consider slow-roll inflation for a single scalar field with an arbitrary potential and an arbitrary non-minimal coupling to the Gauss-Bonnet term. By introducing a combined hierarchy of Hubble and ...
