ABSTRACT
Let G be a group and w = w(x 1, x 2,…, xn ) ∈ F a word in a free group F on {x 1, x 2, …}. Then the verbal subset of G determined by w is V G ( w ) = { w ( g 1 , … , g n ) | g 1 , … , g n ∈ G } . https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780367810603/b7b45e7e-db6c-4882-a65d-08c75e14529e/content/unequ10_135_1.tif"/>
