In order to expand the relevant theory of fractional differential equation systems, a class of coupled φ-Hilfer fractional differential systems with integral boundary conditions was studied. Firstly, the coupled φ-Hilfer fractional differential sys

The focus of our investigation was on determining the existence of solutions for fractional differential equations (FDEs) of order $ 1 < \gamma\leq 2 $ involving the boundary conditions $ \kappa_{0}\phi(0)+\eta_{0}\phi(v) = \mu_{0} $, and $ \kappa_{1

This paper discusses the existence of solutions for fractional differential equations with nonlocal boundary conditions (NFDEs) under essential assumptions. The boundary conditions incorporate a point $ 0\leq c < d $ and fixed points at the end of th
