| Abstract: |
| An result on the existence of positive solutions for higher-order periodic boundary value problem was obtained by employing a new estimate of noncompactness measure and the fixed point index theory of condensing mapping. The conclusions of this paper extend corresponding results. |
| Key words: periodic boundary value problem closed convex cone positive solution condensing mapping fixed point index |
