Resumen:
We describe the structure of the cohomology of the filiform Lie algebras $L_n$ and $Q_n$as a module over their (2-dimensional) torus of derivations.Our approach relies on the fact that both filiform algebras have an ideal $h$ of codimension 1 for which the structure of its cohomology under the action of the Levi factor of the algebra of derivations of $h$ is known.
