Extremal black holes in the Hořava–Lifshitz gravity
We study the near-horizon geometry of extremal black holes in the z=3 Hořava–Lifshitz gravity with a flow parameter λ. For λ>1/2, near-horizon geometry of extremal black holes are AdS 2×S ...

Slowly rotating black holes in the Hořava–Lifshitz gravity
We investigate slowly rotating black holes in the Hořava–Lifshitz (HL) gravity. For Λ W =0 and λ=1, we find a slowly rotating black hole of the Kehagias–...

Equations of state in the Brans–Dicke cosmology
We investigate the Brans–Dicke (BD) theory with the potential as cosmological model to explain the present accelerating universe. In this work, we consider the BD field as a perfect fluid with the energy densi...

Future cosmological evolution in f(R) gravity using two equations of state parameters
We investigate the issues of future oscillations around the phantom divide (FOPD) for f(R) gravity. For this purpose, we introduce two types of energy density and pressure arisen from the f(R)-higher order curvat...

The absence of the Kerr black hole in the Hořava–Lifshitz gravity
We show that the Kerr metric does not exist as a fully rotating black hole solution to modified Hořava–Lifshitz (HL) gravity with Λ W =0 and λ=1. We do t...
