Abstract

This paper investigates the existence of positive solutions for \(n\)th-order (\(n\ge 3\)) singular sub-linear boundary value problems with all derivatives. A necessary and sufficient condition for the existence of \(C^{n-1}[0,1]\) positive solutions is given by constructing lower and upper solutions and with the comparison theorem. Our nonlinearity \(f(t,x_1,x_2,\ldots ,x_n)\) may be singular at \(x_i=0,\ i=1, \ 2,\ \ldots ,\ n, \ t=0\) and /or \(t=1\).
