Resum
In this paper we investigate a non-reflecting boundary condition (NRBC) of Sommerfeld type for the wave equation in mixed form in time domain. we apply the NRBC to the wave equation in mixed form in time domain for three variational forms of the equation. Special emphasis is put in the spaces where the solution belongs, in particular the regularity required on the boundary. Then stabilized finite element methods are described. Stability and convergence analysis of stabilized finite element formu...
