**The use of the invariant Laplace wave equation on galaxies**

solve the transformed equation and the boundary condition at x 0. To see how to choose represents the wave form f propagating from L to R into the region x 0 while u x,t L 1 f s e x a s f t ax H t xa represents the wave form f propagating from R to L out of the region x 0 . Then the solution that is relevant for our problem is the wave that travels from L to R into the region x 0 . 3... The wave equation, heat equation and Laplace’s equations are known as three fundamental equations in mathematical physics and occur in many branches of physics, in applied mathematics as well as in engineering.
