MULTIPLE SOLUTION FOR SOME p-KIRCHHOFF PROBLEMS WITH ψ-HILFER DERIVATIVE.

In this paper, we will develop the variational framework for some Kirchhoff problems involving both the p-Laplace operator and the ψ-Hiller derivative. Precisely, we use the Mountain pass theorem and Ekland's variational principle to prove the existence ol multiple. Our main result generalizes the paper of César, Adv. Nonlinear Anal., 5(2) (2016), 133-146.. [ABSTRACT FROM AUTHOR]
