The pullback- D attractors for the 3D Kelvin-Voigt-Brinkman-Forchheimer system with delay

摘要

Under some assumptions on the external force f(t,u(t-(t))), the 3D Kelvin-Voigt-Brinkman-Forchheimer system with continuous delay is considered. After the existence of pullback- D absorbing sets for the continuous solution process, the asymptotical compactness obtained by the decomposition method leads to the existence of pullback- D attractors.
