The fixed point approach is utilized to prove the existence and uniqueness of mild solutions for the proposed problem. In the end, the derived results are validated through an illustrative example. � 2023 The Author(s)en-USBanach contraction principleDelay functionsFractional differential equationsFractional integral boundary conditionsHilfer and Erd�lyi�kober fractional operatorsKrasnosellki's fixed point theoremUlam�Hyers stabilityArticlehttps://linkinghub.elsevier.com/retrieve/pii/S2666720723000802
