چکیده
A theorem on higer-order derivative theories of gravity is proved. We find that the de Sitter/anti-de Sitter metric always a solution any generally covariant theory gravity. With this and general form entropy function for spacetimes, we show how to calculate spacetime in without knowing details modified metric. As an example, formula dS Lovelock obtained.

Anti-de Sitter-wave solutions of higher derivative theories.
We show that the recently found anti-de Sitter (AdS)-plane and AdS-spherical wave solutions of quadratic curvature gravity also solve the most general higher derivative theory in D dimensions. More generally, we show that the field equations of such theories reduce to an equation linear in the Ricci tensor for Kerr-Schild spacetimes having type-N Weyl and type-N traceless Ricci tensors.
متن کاملBlack Hole Entropy for Two Higher Derivative Theories of Gravity
The dark energy issue is attracting the attention of an increasing number of physicists all over the world. Among the possible alternatives to explain what as been named the “Mystery of the Millennium” are the so-called Modified Theories of Gravity. A crucial test for such models is represented by the existence and (if this is the case) the properties of their black hole solutions. Nowadays, to...
متن کاملBlack holes in higher-derivative gravity theories.
We study static spherically symmetric solutions of Einstein gravity plus an action polynomial in the Ricci scalar, R, of arbitrary degree, n, in arbitrary dimension, D. The global properties of all such solutions are derived by studying the phase space of field equations in the equivalent theory of gravity coupled to a scalar field, which is obtained by a field redefinition and conformal transf...
متن کاملDe Sitter space versus Nariai Black Hole : stability in d 5 higher derivative gravity
d5 higher derivative gravity on the Schwarzschild-de Sitter (SdS) black hole background is considered. Two horizons SdS BHs are not in thermal equilibrium and Hawking-Page phase transitions are not expected there, unlike to the case of AdS BHs. It is demonstrated that there exists the regime of d5 theory where Nariai BH which is extremal limit of SdS BH is stable. It is in the contrast with Ein...
متن کاملGravity in higher codimension de Sitter Brane Worlds
We study solutions of Einstein’s equations corresponding codimension n > 2 global topological defects with de Sitter slices. We analyze a class of solutions that are cylindrically symmetric and admit positive, negative or zero Bulk cosmological constant. We derive the relevant graviton equations. For an extended brane, the properties of the solution depend on appropriate boundary conditions tha...
