本文研究了四阶奇异非局部边值问题三个正解的存在性。利用Leggett-Williams不动点定理证明了该方程存在三重对称正解。本文的结论本质上推广和改进了某些已知结果。MSC：34B16。
In this paper, we study the existence of three positive solutions for fourth-order singular nonlocal boundary value problems. We show that there exist triple symmetric positive solutions by using Leggett-Williams fixed-point theorem. The conclusions in this paper essentially extend and improve some known results. MSC: 34B16.
