Under the assumption that the nonlinearity is analytic with respect to unknown dependent function, we prove the convergence of a global solution to an equilibrium as time goes to infinity by means of a suitable Łojasiewicz-Simon type inequality with boundary term. Estimates of convergence rate are also provided.25 pagesAnalysis of PDEs35B40,80A22text
