摘要
By using the Guo-Krasnosel'skii fixed point theorem and some height functions defined on special bounded sets, we investigate the existence and multiplicity of positive solutions for a class of nonlinear singular Riemann-Liouville fractional differential equations with sign-changing nonlinearities, subject to Riemann-Stieltjes boundary conditions which contain fractional derivatives.
