Abstract:The paper investigates longtime dynamics of the Kirchhoff wave equation with strong damping and critical nonlinearities: utt?(1+??u2)Δu?Δut+h(ut)+g(u)=f(x), with ?0,1]. The well-posedness and the existence of global and exponential attractors are established, and the stability of the attractors on the perturbation parameter ? is proved for the IBVP of the equation provided that both nonlinearities h(s) and g(s) are of critical growth.
Keywords:Kirchhoff wave equation  Critical exponent  Well-posedness  Global attractor  Exponential attractor  Stability
