Abstract

We consider the following quasilinear elliptic system in a Sobolev space with variable exponent:
$-\text{div}(a(|Du|)Du)=f,$
where $a$ is a $C^1$-function and $f\in W^{-1,p'(x)}(\Omega;\R^m)$. We use the theory of Young measures and weak monotonicity conditions to obtain the existence of solutions.
