Shengli Xie,Yiming Xie
Keywords:Higher-order nonlinear fractional differential equations, positive solution, cone, fixed point index.
Abstract:
      The paper deals with the existence and multiplicity of positive solutions for a system of higher-order nonlinear fractional differential equations with nonlocal boundary conditions. The main tool used in the proof is fixed point index theory in cone. Some limit type conditions for ensuring the existence of positive solutions are given.
