Abstract: The existence of positive solutions to singular fourth-order boundary value problems with two parameters is considered,where the nonlinear term f(t,x,y) may be singular at x=0,y=0.The main tool is the fixed point theorem in cone.When λ lies in certain range,the boundary  value problem in question has at least one positive solution.

Key words: singular boundary value problem, positive solutions, cone, fixed point theorem, compact operator
