چکیده	In 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
