On a ψ-Hilfer fractional p -Laplacian differential equation: Existence and multiplicity results

In this paper, we investigate the existence and multiplicity of weak solutions for a class of nonlinear boundary value problems driven by a [Formula: see text]-Hilfer fractional p-Laplacian operator. By introducing an appropriate fractional derivative Banach space, we establish a variational framework that allows the a...
