Existence of Positive Solutions for the Second Order Semipositone m-Point Boundary Value Problem on Time Scales

In this paper, by using Krasnoselskii fixed point theorem, we study the existence of at least one or two positive solutions for the second order semipositone m-point boundary value problem on time scales. We emphasize that the nonlinear term f may take a negative value. As an application, we also give some examples to illustrate our results. © 2014 Foundation for Scientific Research and Technological Innovation.
