Positive solutions of a boundary-value problem for a differential equation with damping and actively bounded delayed forcing term. <i>Electronic Journal of Differential Equations, 2006</i>(73), pp. 1-12.1072-6691https://hdl.handle.net/10877/13946Sufficient conditions are given for the existence of positive solutions of a boundary-value problem concerning a second-order delay differential equation with damping and forcing term whose the delayed part is an actively bounded function, a meaning which is introduced in this paper. The Krasnoselskii fixed point theorem on cones in Banach spaces is used.Text12 pages1 file (.pdf)enAttribution 4.0 InternationalBoundary value problemsDelay differential equationsPositive solutionsKrasnoselskii fixed point theoremArticle
