On a p(x)-biharmonic Kirchhoff type problem with indefinite weight and no flux boundary condition

Existence of two non-zero weak solutions for a $p(\cdot)$-biharmonic problem with Navier boundary conditions

“…• elliptic problems involving p. /-biharmonic operator with different boundary conditions (see for instance [2,3,10,13,15,16,18,20,22,23,25,27,29,32,37,38,40,41,43]).…”
