Positive solutions of a boundaryvalue problem for a
differential equation with damping and actively bounded
delayed forcing term
George L. Karakostas
Abstract:
Sufficient conditions are given for the existence of
positive solutions of a boundaryvalue problem concerning a
secondorder 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.
