Abstract:We introduce some most important operators in harmonic analysis and tell how these operators connect with each other，and how they are related to the wave propagator. Particularly, we study the damped wave equation whose solution behaves like the heat operator in its low frequency part and like the wave propagator in its high frequency part.
