Abstract : Let $X$ be a divergence-free vector field defined on a closed, connected Riemannian manifold. In this paper, we show the equivalence between the following conditions:
$\bullet$ $X$ is a divergence-free vector field satisfying the shadowing property.
$\bullet$ $X$ is a divergence-free vector field satisfying the Lipschitz shadowing property.
$\bullet$ $X$ is an expansive divergence-free vector field.
$\bullet$ $X$ has no singularities and is Anosov.
Keywords : shadowing, Lipschitz shadowing, expansiveness, Anosov vector fields
