摘要 利用锥上不动点指数理论。给出了下列m-点边值问题u^(n)+f(t,u)=0,0〈t〈1满足边界条件u^(i)(0)=0,i=0,1,…,n-2,u^(n-2)(1)=∑i=1^m-2aiu^(n-2)(ξi)的多个正解的存在性,其中ai≥0,i=0,1,…,m-3,am-2〉0,0〈ξ1〈ξ2〈…〈ξm-2〈1,∑i-1^m-2aiξi〈1,ai,i=1,2,…,m-2,为给定的常数. By using a fixed point index theory in cones, the existence of multiple positive solutions to the boundary value problem is givea,u^(n)+f(t,u)=0,0〈t〈1 subject to the boundary conditions u^(i)(0)=0,i=0,1,…,n-2,u^(n-2)(1)=∑i=1^m-2aiu^(n-2)(ξi) where ai≥0,i=0,1,…,m-3,am-2〉0,0〈ξ1〈ξ2〈…〈ξm-2〈1,∑i-1^m-2aiξi〈1,ai,i=1,2,…,m-2,are given constants.
