... equation 1.1. By the use of the fixed point theorem of cone expansion and compression type, results on the existence of positive solutions to the BVP 1.1 areestablished. The paper is organized ... follows. In Section 2, we give some lemmas, which will berequired in the proof of our main theorem. In Section 3, we prove some theorems on the existence of positive solutions for BVP 1.1. ... Khan, J. J. Nieto, and V.
