摘 要: | 考虑一维p—laplacian非线性边值问题:(φ(x’))'+f(t,x,y)=0,(φp(x)’)’+g(t,x,y,)=0,其中φp(s)=|s|^p-2s,p〉1.通过应用krasnoselskii锥不动点定理,建立了该问题存在多个正解的充分条件,推广并丰富了以往文献的一些结论.

Abstract: | This paper deals with nonlinear boundory value problem with one - dimensional p - laplacian ( φp ( x' ) )' + f( , tx, y) = 0, ( φp ( x)')' + g( t, x, y) = 0, t ∈ (0,1), where φp (s) = |s|^p-2 s ,p 〉 1. By using Kranoselskii fixed - point theorem in cones, we establish sufficient conditions for the multiplicity of positive solutions of this problem. |
