摘要:

 利用非线性Leray-Schauder抉择定理和锥不动点定理, 在假设条件下证明一维非线性奇异p-Laplacian三点边值问题解的存在性. 结果表明, 在区间(0,1]上至少存在一个正解.

关键词:  Leray-Schauder抉择定理, 锥不动点定理, 奇异边值问题, 正解的存在性

Abstract:

 By means of nonlinear Leray-Schauder alternative theorem and fixed point theorem in cones, the authors proved the existence of the solutions for one-dimensional singular p-Laplacian three-point boundary value problems under assumptive conditions. There is at least one positive value in the interval from zero to one.

Key words: LeraySchauder alternative theorem, fixed point theorem in cones, singular boundary value problem, existence of positive solution
