Abstract: (arXiv)
The stability of de Sitter spacetime in Horava-Lifshitz theory of gravity with projectability but without detailed balance condition is studied. It is found that, in contrast to the case of the Minkowski background, the spin-0 graviton now is stable for any given ξ\xi, and free of ghost for ξ0\xi \le 0 in the infrared limit, where ξ\xi is the dynamical coupling constant.
