摘要:The dynamics of a dissipative PDE can be reduced to a explicit system of ODEs by constructing inertial manifold. However, due to the required spectral gap condition, the known applications were mainly restricted to the PDEs defined on periodic domains with dimension two or three, and usually no longer valid for the space dimensions d≥4 or general bounded domains. In this talk, we introduce some theories of bi-Lipschitz Mane projections and provide a criterion which can realize the finite-dimensional reduction and deal with the case of multi-dimensional general bounded domains (aperiodic). As an example, we give the bi-Lipschitz Mane projections for a class of fractional Cahn-Hillard equations with Kirchhoff-type nonlinearity.
