Existence of positive solutions for 2n2nth-order singular superlinear boundary value problems

This paper investigates the existence of positive solutions for 2n2nth-order (n>1n>1) singular superlinear boundary value problems. A necessary and sufficient condition for the existence of C2n−2[0,1]C2n−2[0,1] as well as C2n−1[0,1]C2n−1[0,1] positive solutions is given by constructing a special cone and with the ee-Norm.
