Zhao, Zengqin Positive solutions for singular three-point boundary-value problems. (English) Zbl 1142.34323 Electron. J. Differ. Equ. 2007, Paper No. 156, 8 p. (2007). Summary: We present the Green’s function for a second-order linear differential equation with three-point boundary conditions. We give the exact expressions of the solutions for the linear three-point boundary problems by means of the Green’s function. As applications, we study uniqueness and iteration of the solutions for a nonlinear singular second-order three-point boundary value problem.
