A Note on Friedmann Equation of FRW Universe in DeformedHov{r}ava-Lifshitz Gravity from Entropic Force

With entropic interpretation of gravity proposed by Verlinde, we obtain the Friedmann equation of the Friedmann-Robertson-Walker universe for the deformed Hov{r}ava-Lifshitz gravity. It is shown that, when the parameter of Hov{r}ava-Lifshitz gravityω→∝, 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 Hov{r}ava-Lifshitz gravity.
