We provide a new multiplicity result for a weighted $ p(x) $-biharmonic problem on a bounded domain $ \Omega $ of $ \mathbb R^n $ with Navier conditions on $ \partial\Omega $. Our approach, of variational nature, requires a suitable oscillating behavior of the nonlinearity and the associated weight to be compactly supported in $ \Omega $.

Keywords: p(x)-biharmonic operator, Navier conditions, multiplicity, variational methods.
