Abstract
Conditions for the functionals contained in the Five Functionals Fixed Point Theorem are
determined to guarantee the existence of at least two positive xed points for a nonlinear
operator. For the second order boundary value problem, y
HH + f (y) = 0, 0 t 1,
y(0) = 0 = y(1), where f : R ! [0; 1); growth conditions are imposed on f which yield
the existence of at least two positive solutions. We then make a comparison to the growth
