We study the existence and nonexistence of positive solutions for a system of Riemann–Liouville fractional differential equations with p-Laplacian operators, nonnegative nonlinearities and positive parameters, subject to coupled nonlocal boundary conditions which contain Riemann–Stieltjes integrals and various fractional derivatives. We use the Guo–Krasnosel’skii fixed point theorem in the proof of the main existence results.

具有p -Laplacian算子的Riemann-Liouville分数阶边值问题系统的正解

我们研究的存在性和正解的不存在对黎曼-刘维分数阶微分方程的与系统p -Laplacian运营商，非负非线性和正参数，但须含有黎曼- Stieltjes积分各种分数衍生物耦合非局部边界条件。在主要存在结果的证明中，我们使用了Guo–Krasnosel'skii不动点定理。
