In science:

The basic quasi-isometry invariants for a finitely-generated nilpotent group G are most easily computed in terms of the set {ci (G)} of ranks (over Q) of the quotients Gi /Gi+1 of the lower central series for G, where Gi is defined inductively by G1 = G and Gi+1 = [G, Gi ].
Problems on the geometry of finitely generated solvable groups
Thus, a character of Q is a series W ∈ bD such that hW | 1i = 1 and hW | F Gi = hW | F i hW | Gi for all F , G ∈ Q.
Random walks on quasisymmetric functions
The series {π(Gi )} of normal subgroups of π(G) = G/MG descends from G/MG = V ⋊H to 1.

We call the sequence Gi an almost derived series.

Subsequently, a series of contributions were made to reduce the dimensions to n ≥ 5 by a number of authors (see [Ba], [Bo], [G2], [Gi], [Pa], and [Z1]).
