Abstract

We establish existence results of the following three-point boundary value problems:


where and with or with The approach applied in this paper is upper and lower solution method associated with basic degree theory or Schauder’s fixed point theorem. Under the Nagumo’s condition posed on the source term, we deal with diverse solutions for this boundary value problem with the function fwhich is continuous, Carathéodory on its domain, respectively.
