Wave propagation in viscoelastic materials

Description:  Here we present a study of a problem that describes the displacement of a wave in a viscoelastic material. To the problem are established existence, uniqueness and stability results. Furthermore, a numerical method is proposed, a semi-discrete defined over a non-uniform partition and the fully discrete adding a temporal integration. It is proved that both methods have quadratic spatial convergence and, in the case of the discrete method, the convergence in time is of first order.
