摘要: 该文通过利用Leggett-Williams定理,建立了一维奇异p-Laplacian非线性边值问题(\varphi(u'))'+a(t)f(u)=0,\u'(0)=u(1)=0 (或者u(0)=u'(1)=0),其中\varphi(s)=|s|^{p-2}s, p>1三解的存在性定理,推广并丰富了以往文献的一些结论.

Abstract: This paper deals with the existence of multiple solutions for the singularp-Laplacian nonlinear BVP (\varphi(u'))'+a(t)f(u)=0,\ u'(0)=u(1)=0 (or u(0)=u'(1)=0), where \varphi(s)=|s|^{p-2}s,\ p>1. Sufficient conditions are established for the multiplicity of solutions of this problem by using Leggett-Williams theorem.The results presented here generalize many known results
