RT Journal Article T1 System of fractional boundary value problem with p-Laplacian and advanced arguments A1 Mahdjouba, Amina A1 Nieto Roig, Juan José A1 Ouahab, Abdelghani K1 Fractional differential equations K1 p-Laplacian operator K1 Cone K1 Fixed point theorem K1 Positive solutions K1 Multiplicity of solutions AB In this paper, we discuss the existence and multiplicity of positive solutions for a system of fractional differential equations with boundary condition and advanced arguments. The existence result is proved via Leray–Schauder’s fixed point theorem type in a vector Banach space. Further, by using a new fixed point theorem in order Banach space, we study the multiplicity of positive solutions. Finally, some examples are given to illustrate our results PB Springer SN 1687-1839 YR 2021 FD 2021 LK http://hdl.handle.net/10347/26778 UL http://hdl.handle.net/10347/26778 LA eng NO Adv Differ Equ 2021, 352. https://doi.org/10.1186/s13662-021-03508-4 NO The research of J.J.
