We use variational methods for smooth functionals defined on reflexive Banach spaces in order to achieve our results. Also by presenting an example, we ensure the applicability of our results.", keywords = "multi-point boundary value problem, impulsive condition, classical solution, variational method, three critical points theorem", issn = "1232-9274" }
