Stability of the de Sitter spacetime in Horava-Lifshitz theory
Abstract
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 , and free of ghost for 0 in the infrared limit, where is the dynamical coupling constant.
