Title: Positive solutions of a three-point boundary-value problem for
       differential equations with damping and actively bounded delayed
       forcing term

Author: George L. Karakostas (Univ. of Ioannina, Greece)

Abstract: 
 We provide sufficient conditions for the existence of positive
 solutions of a three-point 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 introduced in [19]. By writing the damping term
 as a difference of two factors one can extract more information on
 the solutions. (For instance, in an application, given in the last
 section, we can give the exact value of the norm of the solution).
