摘　　要：考虑了一类具有p-Laplacian算子同时非线性项含积分项的Riemann-Liouville型非线性分数阶微分方程,分析其在包含参数及分数阶积分条件的边界条件下的多重正解的存在性.利用格林函数将问题转化为积分方程,并在Banach空间中运用Leggett-Williams不动点定理和广义Avery-Henderson不动点定理获得主要结果,通过一个实例说明所得结果的适用性.A class of nonlinear fractional differential equations of Riemann-Liouville type with p-Laplacian operator and nonlinear terms containing an integral term is considered.The focus is on analyzing its existence of multiple positive solutions under the boundary conditions including a parameter and fractional integral conditions.The problem is transformed into an integral equation by using the Green function.The main results are derived using the Leggett-Williams fixed point theorem and the generalized Avery-Henderson fixed point theorem in the Banach space.The applicability of the result is illustrated by an example.
