Qualitative properties for a class of non-autonomous semi-linear 3rd order PDE arising in dissipative problems

Abstract

We extend previous results regarding the stability and attractivity of solutions u of a large class of initial-boundary-value problems associatede to a non-autonomous semi-linear 3rd order PDE arising in dissipative problems. In the analysis we use Liapunov functionals depending on two parameters, which we adapt to the `error'
