Our approach is based on the Krasnosel'skiĭ-Guo fixed point theorem in cones and the properties of the Green's function corresponding to the BVP under study. The main results are illustrated by suitable examples. KW - boundary value problem KW - nonlocal boundary conditions KW - positive solution KW - cone SN - 1232-9274 ER -
