%X In this paper, the authors study the existence and multiplicity of two point BVP for a singular nonlinear fourth order ordinary differential system by using the fixed-point index theory. The existence and multiplicity theorems on positive solutions are established by using the first eigenvalue of the corresponding linear problems.
