A conservative spectral method is proposed to solve several two-dimensional nonlinear wave equations. The conventional fast Fourier transform is used to approximate the spatial derivatives and a three-level difference scheme with a free parameter ΞΈ is to advance the solution in time. Our time discre

β¦ Synopsis
We study a nonlinear wave equation on the two-dimensional sphere with a blowing-up nonlinearity. The existence and uniqueness of a local regular solution are established. Also, the behavior of the solutions is examined. We show that a large class of solutions to the initial value problem quench in finite time.  2002 Elsevier Science (USA)
