Free groups and projective groups
View through CrossRef
Abstract
Free groups play as important a role in profinite group theory as in abstract group theory. Free profinite groups are defined, like free abstract groups, by a universal property, and epimorphisms from them provide a useful means for studying arbitrary profinite groups.
