WitrynaA completion of the torsion-free locally nilpotent group G is defined to be an arbitrary minimal complete torsion-free locally nilpotent group G* containing G. Consequently, it follows that a complete torsion-free locally nilpotent group G* is the completion of its subgroup G if and only if some positive power of each element of G* belongs to G. Witrynaconnected nilpotent Lie groups (see [10]) and for connected nilpotent Lie groups with non-compact centre (see [2]) yield the following: Theorem 5.1.

WitrynaPublished 2024. Mathematics. Among the most important tools in the study of locally nilpotent derivations (LNDs) of commutative rings are its Z-gradings and the homogeneous derivations associated to them. Gradings which involve other totally ordered abelian groups have also been used to study LNDs, though to a lesser extent.
