Abstract

We will find conditions on f that lead to the existence of at least three positive solutions to the three-point boundary value problem -x@?(t) + f (x(t)) = 0, with x(0) = x'(t"2) = x''(1) = 0, on [0,1], where t"2 @e [12,1). A positive solution will mean a solution in the cone of nonnegative functions in the Banach space C[0,1] with the sup norm.
