Field equations for gravity: An alternative route
We present an alternative derivation of the gravitational field equations starting from the Newton’s law, which intrinsically brings in observer dependence in the theory. Projecting the Riemann curvature tensor appropriately as fit for an observer, taking a cue from Poisson’s equation, the Einstein’s equations immediately follow. Our derivation naturally adapts to Lovelock gravity theories wher...
متن کاملIntersecting 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 کاملUniversal regularization prescription for Lovelock AdS gravity
A definite form for the boundary term that produces the finiteness of both the conserved quantities and Euclidean action for any Lovelock gravity with AdS asymptotics is presented. This prescription merely tells even from odd bulk dimensions, regardless the particular theory considered, what is valid even for Einstein-Hilbert and Einstein-Gauss-Bonnet AdS gravity. The boundary term is a given p...
متن کاملBlack-hole thermodynamics in Lovelock gravity.
five dimensions, one finds that the specific heat of a black hole becomes positive at small mass, allowing the black hole to achieve stable equilibrium with its environment and giving it an infinite lifetime. This behavior is not universal, however, but it always occurs in 2k+1 dimensions for a Lovelock theory including the 2k-dimensional Euler density. For theories including six-derivative or ...
