Abstract
We derive the hydrodynamic equations for the supersolid and superhexat ic phases of a neutral two-dimensional Bose fluid. We find, assuming t hat the normal part of the fluid is clamped to an underlying substrate , that both phases can sustain third-sound modes and that in the super solid phase there are additional modes due to the superfluid motion of point defects (vacancies and interstitials).
