Boundary Value Problems 2014, 2014:125  doi:10.1186/1687-2770-2014-125

We consider the following complementary Lidstone boundary value problem:

<a onClick="popup('http://www.boundaryvalueproblems.com/content/2014/1/125/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.boundaryvalueproblems.com/content/2014/1/125/mathml/M1">View MathML</a>

By using fixed point theorems of Leggett-Williams and Avery, we offer several criteria for the existence of three positive solutions of the boundary value problem. Examples are also included to illustrate the results obtained. We note that the nonlinear term F depends on <a onClick="popup('http://www.boundaryvalueproblems.com/content/2014/1/125/mathml/M2','MathML',630,470);return false;" target="_blank" href="http://www.boundaryvalueproblems.com/content/2014/1/125/mathml/M2">View MathML</a> and this derivative dependence is seldom investigated in the literature and a new technique is required to tackle the problem.
