Min-max method for some classes of Kirchhoff problems involving the $\psi$-Hilfer fractional derivative

Source abstract

<abstract><p>In this work, we develop some variational settings related to some singular $p$-Kirchhoff problems involving the $\psi$-Hilfer fractional derivative. More precisely, we combine the variational method with the min-max method in order to prove the existence of nontrivial solutions for the given problem. Our main result generalizes previous ones in the literature.</p></abstract>
