Electronic Journal of Differential Equations, 2022(31), pp. 1-14.1072-6691https://hdl.handle.net/10877/16590In this article, we apply the method of lower and upper solutions for studying delay evolution equations with nonlocal and impulsive conditions in infinite dimensional Banach spaces. Under wide monotone conditions and noncompactness measure condition of nonlinear term, we obtain the existence of extremal solutions and a unique solution between lower and upper solutions. A concrete application to partial differential equations is considered.Text14 pages1 file (.pdf)enAttribution 4.0 InternationalEvolution equationsDelayNonlocal and impulsive conditionsLower and upper solutionsMeasure of noncompactnessArticle
