%0 Journal Article %T Positive solutions for fractional differential equation involving the Riemann-Stieltjes integral conditions with two parameters %A Wang, Ying %J Journal of Nonlinear Sciences and Applications %D 2016 %V 9 %N 11 %@ ISSN 2008-1901 %F Wang2016 %X Through the application of the upper-lower solutions method and the fixed point theorem on cone, under certain conditions, we obtain that there exist appropriate regions of parameters in which the fractional differential equation has at least one or no positive solution. In the end, an example is worked out to illustrate our main results. %9 journal article %R 10.22436/jnsa.009.11.02 %U http://dx.doi.org/10.22436/jnsa.009.11.02 %P 5733--5740
