Positive solutions for a class of singular semipositione fractional difference system with coupled boundary conditions

AI Shangming;LU Yuanxiu;GAO Peng;GE Qi;Department of Mathematics,College of Sciences,Yanbian University;  
In this paper,we study the existence of positive solutions for a singular semipositone fractional difference system with coupled boundary conditions.This paper analyzes some characteristics of the Green's function.By fixed point theorem in cone of Banach space,we prove the existence of positive solutions to this system when parameterλbelongs to different interval.Finally,an example is given to demonstrate the validity of our main results.
