| contents | This paper is concerned with the long-time dynamics of semilinear wave equation subject to dissipative boundary condition. To do so, we first analyze the set of equilibria, and show it could contain infinitely many elements. Second, we show that, for some nonlinear interior sources, the wave equations have solutions that do not stabilize to any single function, while they approach a continuum of such functions. Finally, if the interior source is a Łojasiewicz-type function, the solution of the wave equation converges to an equilibrium at a rate that depends on the Łojasiewicz exponent, although the set of equilibria is infinite. |
