Some sufficient conditions related to w-periodicity of solutions were obtained by using coincidence degree theory. In a particular case, an application showing the accuracy of our results was given.eninfo:eu-repo/semantics/closedAccessCoincidence Degree TheoryDifferential EquationPeriodic SolutionsArticle122N/AQ37281WOS:000648311100005
