چکیده
In this study we present evolving wormhole configurations in third-order {Lovelock} gravity and investigate the possibility that these solutions satisfy energy conditions. Using a generalized Friedmann-Robertson-Walker spacetime, derive geometries by considering constraint on Ricci scalar. standard cosmological models, scalar is independent of radial coordinate $r$ only function time. We use property to introduce dynamic expanding an inflationary background explore effects higher-order terms dynamics such wormholes. Our analysis shows for suitable coefficients, there are respect weak condition {(WEC)}. addition this, also other WEC throughout their respective evolution.

Vacuum 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 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 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 ...
متن کاملBlack Holes in Einstein - Lovelock Gravity ∗
Static, spherically symmetric solutions of the field equations for a particular dimensional continuation of general relativity with negative cosmological constant are found. In even dimensions the solution has many similarities with the Schwarzschild metric. In odd dimensions, the equations of motion are explicitly anti de-Sitter invariant, and the solution is alike in many ways to the 2+1 blac...
