Abstract: By means of mixed monotone fixed point theorem, singular second order threepoint continuous and discrete boundary value problems were studied. First, the existence and uniqueness were established for the threepoint continuous boundary value problems of singular second order differential equations. Second, the existence and uniqueness were established for the threepoint discrete boundary value problems of singular second order difference equations.

Key words: singular second order threepoint boundary value problem, positive solutions, existence, uniqueness
