摘要:

利用LeggettWilliams不动点定理和锥上不动点定理,研究一类具有分数线性微分算子的分数阶微分方程边值问题, 得到了该边值问题至少1个正解和至少3个正解的存在性定理.

关键词: 分数线性微分算子, 分数阶微分方程, 边值问题, 不动点定理, 正解

Abstract:

We discussed the existence of positive solutions for a class of boundary value problems of fractional differential equation with fractional linear differential operator. Based on the LeggettWilliams fixed point theorem and the fixed point theorem in cones, the existence theorems of one positive solution or three positive solutions, existed at least, have been established, respectively.

Key words: fractional linear differential operator, fractional differential equation, boundary value problems, fixed point theorem, positive solutions
