摘要In this note we study the linear dynamics of scalar graviton in a de Sitter background in the infrared limit of the healthy extension of Horava-Lifshitz gravity with the dynamical critical exponent z = 3. Both our analytical and numerical results show that the nonzero Fourier modes of scalar graviton oscillate with an exponentially damping amplitude on the subhorizon scale, while on the superhorizon scale, the phases are frozen and they approach to some asymptotic values. In addition, as the case of the nonzero modes on superhorizon scale, the zero mode also initially decays exponentially and then approaches to an asymptotic constant value.
