Abstract
In this paper, we study the existence of positive solutions for the following nonlinear m-point boundary value problem with p-Laplacian:(Ïp(uâ²))â²+a(t)f(u(t))=0,0 1, Ïq=(Ïp)-1,1p+1q=1, 1 ⩽ k ⩽ s ⩽ m â 2, ai, bi â (0, +â) with 0<âi=1kbi-âi=k+1sbi<1,0<âi=1m-2ai<1,0<ξ1<ξ2<â¯<ξm-2<1, a(t) â C((0, 1), [0, +â)), f â C([0, +â), [0, +â)) . We show that there exists one or two positive solutions by using fixed-point theorem for operator on a cone. The conclusions in this paper essentially extend and improve the known results.
