Abstract

element for treating the linear second order hyperbolic
initial-boundary value problem. We prove a posteriori $L^2(L^2)$
and error estimates for this method under minimal regularity
hypothesis. Test problem of an application of the wave equation
in the laser is presented to verify the efficiency and accuracy
of the method.
