Lower Central Series,t ordinal ., .(.) = ∩. .(.), where for subsets . of ., [.] denotes the subgroup of . generated by all commutators [.] := . = . . ∈ . ∈ .. The group . is said to be . if .(.) = 1 for some ordinal ., or simply . if . is a finite ordinal. In particular, if .(.) = 1, where . is the least infinite ordina

Derived Series,ived series of free nilpotent groups. Our main aim in this Chapter, however, is the study of the transfinite terms of the derived series of groups. We give an account of the homological approach of R. Strebel . The impact on the asphericity conjecture of J. H. C. Whitehead is also exp
