Abstract
In the present paper, using variational approach and the
theory of the variable exponent Lebesgue spaces, the existence of nontrivial
weak solutions to a fourth order elliptic equation involving a
$p(x)$-biharmonic operator
and a concave-convex nonlinearity the Navier boundary
conditions is obtained.
