Abstract:
In this work we study the global well-posedness, dissipativity and existence of
global attractors for Kirchhoff type plate equations with nonlocal weak damping and
anti-damping, when the nonlinear term \(g(u)\) satisfies a subcritical growth condition.
Firstly, we show the global well-posedness of this system by the monotone operator
theory with locally Lipschitz perturbation.
Secondly, we construct a refined Gronwall's inequality and then apply the barrier
method to prove the dissipativity for this system. Lastly, the asymptotic smoothness
by taking advantage of the energy reconstruction method, we deduce the existence of
a global attractor for this system.
