摘要

We consider the nonautonomous viscoelastic wave equation with analytic nonlinearity and time varying delay. By construction of a suitable Lyapunov energy and by using the Łojasiewicz-Simon inequality we show that, when the amplitude of the time delay is small enough, the dissipation given by the viscoelastic term is strong enough to prove the convergence to equilibrium as well as estimates for the rate of convergence for any global bounded solution.
