We consider the wave equation in a bounded region with a smooth boundary with distributed delay on the boundary or into the domain. In both cases, under suitable assumptions, we prove the expo- nential stability of the solution. These results are obtained by introduc- ing suitable energies and by proving some observability inequalities. For an internal distributed delay, we further show some instability results.

Abstract: | We consider the wave equation in a bounded region with a smooth boundary with distributed delay on the boundary or into the domain. In both cases, under suitable assumptions, we prove the expo- nential stability of the solution. These results are obtained by introduc- ing suitable energies and by proving some observability inequalities. For an internal distributed delay, we further show some instability results. |
