In this paper, we obtain the lower-dimensional limits $(p=2,3,4,5,6)$ of cubic Lovelock gravity through a regularized Kaluza-Klein reduction. By taking flat internal space for simplicity, also study static black hole solutions in resulting theories. We show that match with ones obtained from "naive limit" $D$-dimensional equation metric function, which is by first scaling relevant couplings fac...

In the paper, hep-th/0501055 (R. it is shown that by applying the first law of thermodynamics to the apparent horizon of an FRW universe and assuming the geometric entropy given by a quarter of the apparent horizon area, one can derive the Friedmann equations describing the dynamics of the universe with any spatial curvature; using the entropy formula for the static spherically symmetric black ...

Abstract In this work, we present the new higher dimensional dyonic black hole solutions of Lovelock-scalar gravity coupled with quasitopological electromagnetism. First, concentrate on dimensionally continued and construct solution that describes holes conformal scalar hair in diverse dimensions. We study physical properties discuss effects electromagnetism field local thermodynamic stability ...

As in the case of Lanczos-Lovelock gravity, main advantage F(T) gravity is said to be that it leads second order field equations, while F(R) theory fourth equations. We show rather a disadvantage, since unresolved issue `Branched Hamiltonian'. The problem bypassed F(R,T) theory.

Thermodynamic aspects of black holes and Rindler horizons are reviewed along with quantum field theory in the corresponding curved spacetimes. The implication that gravity might be thermodynamic in origin is considered. Macroscopic space is seen to emerge at a course-grained limit via the application of holography in the context of horizons. Both Newtonian and Einsteinian gravity are seen (sepe...
