Fractional p-Laplacian Equations with Sandwich Pairs

The main purpose of this paper was to consider new sandwich pairs and investigate the existence of a solution for a new class of fractional differential equations with p-Laplacian via variational methods in psi-fractional space H-p alpha,beta;psi (Omega). The results obtained in this paper are the first to make use of the theory of psi-Hilfer fractional operators with p-Laplacian.
