Uniqueness of solutions for a ψ -Hilfer fractional integral boundary value problem with the p -Laplacian operator

In this article, we discuss the existence of a unique solution to a ψ ψ -Hilfer fractional differential equation involving the p p -Laplacian operator subject to nonlocal ψ ψ -Riemann-Liouville fractional integral boundary conditions. Banach’s fixed point theorem is the main tool of our study. Examples are given for illustrating the obtained results.
