Abstract
We determine the restricted Lie algebra associated with the Zassenhauss filtration of a right-angled Artin group. We also provide another proof for a result of Koberda saying that the graph is uniquely determined by the first and second cohomology groups, together with the cup product, of the associated right-angled Artin group.
