Utilizing variational methods and applying certain critical point theorems from Ricceri for smooth functionals, we demonstrate the existence of at least three solutions to the problem. To illustrate the practical relevance of our findings, we provide an example at the end.eninfo:eu-repo/semantics/closedAccessThree SolutionsTime ScalesImpulsive EffectsVariational MethodsArticle
