We shall consider a one-dimensional semilinear wave equation in a ΓΏnite interval (0; l) in R. A usual homogeneous boundary condition is imposed on it at x = 0; l. We shall show that the solution u(x; t) oscillates on the time t in the following sense. Let x be any ΓΏxed in (0; l), then u(x; t) change

A new numerical algorithm is developed for the solution of time-dependent differential equations of diffusion type. It allows for an accurate and efficient treatment of multidimensional problems with variable coefficients, nonlinearities, and general boundary conditions. For space discretization we
