Abstract parabolic problems in ordered Banach spaces (Q2773253)

The authors consider abstract parabolic problems in ordered Banach spaces and give conditions under which they have global attractors. Their approach is via comparison of solutions. Within this approach abstract comparison principles are obtained and bounds on the attractors are given by ordered intervals in Banach spaces. These results are applied to ordinary differential equations and to parabolic equations for which the main part is given by a sum of fractional powers of sectorial operators having increasing resolvents and integral operators having positive kernels.
