Global nonexistence for a semilinear wave equation with nonlinear boundary dissipation

Abstract: In this paper, we consider the following problem where is a bounded open interval in , and . We are interested in the interaction between the boundary damping and the interior source . Under some appropriate assumptions on the initial data, two blow-up results with positive initial energy are established. Furthermore, we obtain that the solutions blow up if p or is sufficiently large. [Copyright &y& Elsevier]
