Charlotte Scott Centre for Algebra

New paper by Evgeny Khukhro (Univ. of Lincoln) and Pavel Shumyatsky (Univ. of Brasilia)Strong conciseness of Engel words in profinite groups” has been accepted for publication in a high-ranking  mathematical journal Mathematische Nachrichten. The work stems from the collaboration with University of Brasilia.

Math-NachrAbstract: A group word $latex w$ is said to be strongly concise in a class $latex mathscr C$ of profinite groups if, for any group $latex G$ in $latex mathscr C$, either $latex w$ takes at least continuum many values in $latex G$ or the verbal subgroup $latex w(G)$ is finite. It is conjectured that all words are strongly concise in the class of all profinite groups. Earlier Detomi, Klopsch, and Shumyatsky proved this conjecture for multilinear commutator words, as well as for some other particular words. They also proved that every group word is strongly concise in the class of…
