Intersecting hypersurfaces and Lovelock Gravity
A theory of gravity in higher dimensions is considered. The usual Einstein-Hilbert action is supplemented with Lovelock terms, of higher order in the curvature tensor. These terms are important for the low energy action of string theories. The intersection of hypersurfaces is studied in the Lovelock theory. The study is restricted to hypersurfaces of co-dimension 1, (d− 1)-dimensional submanifo...
متن کاملPerturbative formalism of Lovelock gravity
In this work we develop a perturbative formalism for the treatment of Lovelock theories of gravity. We consider in detail D-dimensional models in Lovelock gravity with an induced metric given by the product of the metrics of two maximally symmetric spaces. We first explicitly obtain the Lovelock action, Hamiltonian constraint, gravitational momenta, and dynamical equations for this type of mini...
متن کاملVacuum static compactified wormholes in eight - dimensional Lovelock theory
In this paper new exact solutions in eight dimensional Lovelock theory will be presented. These solutions are vacuum static wormhole, black hole and generalized Bertotti-Robinson space-times with nontrivial torsion. All the solutions have a cross product structure of the type M5 × Σ3 where M5 is a five dimensional manifold and Σ3 a compact constant curvature manifold. The wormhole is the first ...
متن کاملIntersecting hypersurfaces, topalogical densities and Lovelock Gravity
The situation of intersecting hypersurfaces in classical dimensionally continued Euler density gravity was introduced in our recent work [1]. We wish to simplify and demistify the calculations, providing an interesting geometrical interpretation. This analysis allows us to deal most efficiently with the division of space-time into a honeycomb network of cells which one might expect from membran...
متن کاملIntersecting membranes in AdS and Lovelock gravity
Colliding and intersecting thin membranes of matter are studied in the Lovelock higher order curvature theory of gravity. We restrict the study to constant curvature membranes in constant curvature AdS and dS background and consider their general intersections. This illustrates some key features which make the higher Lovelock theory different to the Einstein gravity. Lovelock terms couple hyper...
