Conformal Isometries and the Wave Equation

A conformal isometry is a transformation of spacetime that leaves the metric invariant up to an overall scale factor that may vary from one point to the next. This article shows that when N≥ 2, the classical wave equation in N-dimensional flat spacetime has symmetries corresponding to all conformal isometries.
