In this paper, we deal with the existence of ω-periodic mild solutions for the abstract evolution equation with delay in an ordered Banach space E u'(t)+Au(t)=F(t,u(t),u(t-τ)), t∈\R, where A:D(A)⊂ E→ E is a closed linear operator and -A generates a positive C0-semigroup T(t)(t≥0), F:\R× E× E→ E is a continuous mapping which is ω-periodic in t, and τ≥0 is a constant. Under some weaker assumptions, we construct monotone iterative method for the delayed evolution equation periodic problems, and obtain the existence of maximal and minimal periodic mild solutions. The results obtained generalize the recent conclusions on this topic. Finally, we present two applications to illustrate the feasibility of our abstract results.
