We emphasize that the nonlinear term f may take a negative value. As an application, we also give some examples to illustrate our results. © 2014 Foundation for Scientific Research and Technological Innovation.en10.1007/s12591-013-0195-1info:eu-repo/semantics/closedAccessFixed point theoremsPositive solutionsSemipositone problemsTime scalesArticle223265280Q3
