Abstract

Given a group-word w and a group G, the set of w-values in G is denoted by Gw and the verbal subgroup w(G) is the one generated by Gw. The word w is concise if w(G) is finite for all groups G in which Gw is finite. We obtain several results supporting the conjecture that the word [u1,…,us] is concise whenever the words u1,…,us are non-commutator.
