摘要 利用锥上不动点理论,借助于R.P.Agarwal和D.O′Regan(J.Math.Anal.Appl.,1999,229:441~451.)的方法研究了一维p Laplacian奇异初值问题[φp(u′)]′=f(t,u,u′), 0<t<1,u(0)=u′(0)=0的正解的存在性,推广了已有的一些结果. In this paper, the existence of positive solutions for the following one-dimensional p-Laplacian singular initial value problem is studied by employing the fixed-point theorem in cones:[φ_p(u′)]′=f(t,u,u′),0<t<1, u(0)=u′(0)=0.The results obtained in this paper extend and improve some existing results.
