Abstract: By using the iterative technique, regularity estimate for semigroup and some a priori estimates, we proved the existence of global attractor for a class of higherorder diffusion equation with Neumann boundary value conditions in fractional order space.

Key words: higherorder diffusion equation, global attractor, a priori estimate
