文摘

In this paper, we study the existence and multiplicity of symmetric positive solutions for a nonlinear system with multi-point coupled boundary conditions. The arguments are based upon a specially constructed cone and the fixed point index theorem in cones. An example is then given to demonstrate the applicability of our results.
