A singular boundary value problem for nonlinear differential equations of fractional order (Q1032538)

The paper studies a Dirichlet boundary value problem for equations of fractional order based on the Riemann Liouville fractional derivative. The authors obtain existence results by using the Leray-Schauder continuation principle and use Hölder's inequality to obtain a priori estimates. The authors also indicate how their methods in this paper may improve the results of other recent papers.
