Multiplicity of positive solutions for higher order Sturm-Liouville problems

We establish the existence of an arbitrary number of positive solutions to the 2mth order Sturm-Liouville type problem (-1)(m)((2m))(y) (t) = f(t,y(t)), 0 less than or equal to t less than or eq ual to 1, alphay((2i))(0) - betay((2i+1))(0) = 0, 0 less than or equal to i less than or equal to m - 1, gammay((2i))(1) + deltay((2i+1))(1) = 0, 0 le ss than or equal to i less than or equal to m - 1, where f : [0, I] x [0, infinity) --> [0, infinity) is continuous. We accomp lish this by making growth assumptions on f which we state in terms which g eneralize assumptions in recent works regarding superlinear and/or sublinea r growth in f.
