"A discussion on the existence of positive solutions of the boundary value problems via ψ-Hilfer fractional derivative on b-metric spaces", Advances in Difference Equations, Vol.2020, No.1.1687-1839https://doi.org/10.1186/s13662-020-03076-zIn this paper, we investigate the existence of positive solutions for the new class of boundary value problems via ψ-Hilfer fractional differential equations. For our purpose, we use the α− ψ Geraghty-type contraction in the framework of the b-metric space. We give an example illustrating the validity of the proved results. © 2020, The Author(s).eninfo:eu-repo/semantics/openAccessFixed PointGeraghty-Type ContractionPositive SolutionΨ-Hilfer Fractional DerivativeA discussion on the existence of positive solutions of the boundary value problems via ψ-Hilfer fractional derivative on b-metric spacesA Discussion on the Existence of Positive Solutions of the Boundary Value Problems Via Ψ-Hilfer Fractional Derivative on B-Metric SpacesArticle2020110.1186/s13662-020-03076-z2-s2.0-85094675685N/AN/A
