Abstract

In this paper, we research the existence and uniqueness of positive solutions for a coupled system of fractional differential equations. By means of some standard fixed point principles, some results on the existence and uniqueness of positive solutions for coupled systems are obtained.

Highlights

  • Fractional differential equations can describe many phenomena in various fields of engineering and scientific disciplines such as control theory, physics, chemistry, biology, economics, mechanics and electromagnetic

  • There are a large number of papers dealing with the existence of positive solutions of boundary value problems for nonlinear differential equations of fractional order

  • In [12], Li, Luo and Zhou considered the existence of positive solutions of the following boundary value problem of fractional order differential equations: D0 u(t) f (t u(t)) 0 0 t 1 u(0) 0 D0 u(1) aD0 u( )

Summary

Introduction

Fractional differential equations can describe many phenomena in various fields of engineering and scientific disciplines such as control theory, physics, chemistry, biology, economics, mechanics and electromagnetic. There are a large number of papers dealing with the existence of positive solutions of boundary value problems for nonlinear differential equations of fractional order. In [30], Yang, Wei and Dong investigated the following existence of positive solutions of fractional order differential equations:. Recently some authors pay close attention to the existence of solutions for coupled systems of fractional differential equations (see[2,3,25,26]). In [26], Su studied the existence of solutions for a coupled system of fractional differential equations: D0 D0. In [25], Sun, Liu and Liu considered the following systems of fractional differential equations with antiperiodic boundary conditions:
