Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
In this paper, the damped wave equation, u(tt) + alpha u(t) =Delta u, on the surface of the sphere is considered. Using Lie symmetry approach, similarity transformations are obtained and certain interesting exact solutions of the damped wave equation are presented.
