New outcomes are obtained in this paper based on the Darbo’s fixed point theorem (DFPT) combined with Kuratowski measure of noncompactness (KMNC). We construct an example to illustrate the validity of the observed results.en-USAttribution 3.0 United StatesAttribution 3.0 United Stateshttp://creativecommons.org/licenses/by/3.0/us/http://creativecommons.org/licenses/by/3.0/us/derivatives and integrals of variable-orderboundary value problemDarbo's fixed point theoremmeasure of noncompactnessUlam-Hyers-Rassias stabilityHadamard derivativederivatives and integrals of variable-orderboundary value problemDarbo's fixed point theoremmeasure of noncompactnessUlam-Hyers-Rassias stabilityHadamard derivativeArticle
