# Higher differentiability for solutions of linear elliptic systems with measure data

• We study the differentiability of the solution of the Dirichlet problem associated to the system

$A(u) \equiv - D_i (A_{ij}(x) D_j u) = \mu$
$u \in W^{1,1}_0$(Ω$, \IR^N)$

where Ω is an open bounded subset of $\IR^n$ $(n \geq 2)$ with $C^1$-boundary, $A$ is an elliptic operator with C 0, α-coefficients ($\alpha \in ]0,1]$) and $\mu$ is a signed Radon measure with finite total variation, satisfying a suitable density condition.
