The author uses the method of upper and lower solutions and the fixed-point index theory to obtain some results on existence, nonexistence, uniqueness, and multiplicity of solutions to a singular system of second-order ordinary differential equations with Dirichlet boundary conditions. This problem is motivated by the search of positive radial solutions to an elliptic system on an exterior domain.
