Existence of solutions for a singular double phase problem involving a $ψ$-Hilfer Fractional operator via Nehari Manifold
In this present paper, we investigate a new class of singular double phase $p$-Laplacian equation problems with a $ψ$-Hilfer fractional operator combined from a parametric term. Motivated by the fibering method using the Nehari manifold, we discuss the existence of at least two weak solutions to such problems when the parameter is small enough. Before attacking the main contribution, we discuss some results involving the energy functional and the Nehari manifold.
