A note on Friedmann equation of FRW universe in deformed Horava-Lifshitz gravity from entropic force
Abstract
With entropic interpretation of gravity proposed by Verlinde, we obtain the Friedmann equation of the Friedmann-Robertson-Walker universe for the deformed Horava-Lifshitz gravity. It is shown that, when the parameter of Horava-Lifshitz gravity ω→ ∞, the modified Friedmann equation will go back to the one in Einstein gravity. This results may imply that the entropic interpretation of gravity is effective for the deformed Horava-Lifshitz gravity.
