Gradings for nilpotent Lie algebras
Eero Hakavuori, Ville Kivioja, Terhi Moisala +1
We present a constructive approach to torsion-free gradings of Lie algebras. Our main result is the computation of a maximal grading. Given a Lie algebra, using its maximal grading…

The Rumin complex on nilpotent Lie groups
Francesca Tripaldi
In this paper an alternative definition of the Rumin complex is presented, one that relies on a different concept of weights of forms. In this way, the Rumin co…
