By refining the conditions imposed on $f$ and finding more suitable upper and lower solution, we remove some key conditions used in [3], and still establish their results. %K Upper and lower solution %K fractional differential equation %K Schauder's fixed point theorem %K positive solution %U http://ejde.math.txstate.edu/Volumes/2013/37/abstr.html
