  • Small doubling in $m$-Engel groups 

    Longobardi, Patrizia؛ Maj, Mercede (University of Isfahan, 2020-12-01)
    We study some inverse problems of small doubling type in the class of $m$-Engel groups‎. ‎In particular we investigate the structure of a finite subset $S$ of a torsion-free $m$-Engel group if $|S^2| = 2|S|+b$‎, ‎where $0 ...

  • On finite-by-nilpotent profinite groups 

    Detomi, Eloisa؛ Morigi, Marta (University of Isfahan, 2020-12-01)
    Let $gamma_n=[x_1,ldots,x_n]$ be the $n$th lower central word‎. ‎Suppose that $G$ is a profinite group‎ ‎where the conjugacy classes $x^{gamma_n(G)}$ contains less than $2^{aleph_0}$‎ ‎elements‎ ‎for any $x in G$‎. ‎We ...

  • Some remarks on unipotent automorphisms 

    Puglisi, Orazio؛ Traustason, Gunnar (University of Isfahan, 2020-12-01)
    An automorphism $alpha$ of the group $G$ is said to be $n$-unipotent if $[g,_nalpha]=1$ for all $gin G$‎. ‎In this paper we obtain some results related to nilpotency of groups of $n$-unipotent automorphisms of solvable ...

  • Open problems from the conference ‎"Engel Conditions in Groups‎" ‎held in Bath‎, ‎UK‎, ‎2019 

    Traustason, edited by Gunnar (University of Isfahan, 2020-12-01)
    Here is list of open problems from the conference Engel Type Conditions in Groups in Bath that was held in April 2019.

  • Algorithmic problems in Engel groups and cryptographic applications 

    Kahrobaei, Delaram؛ Noce, Marialaura (University of Isfahan, 2020-12-01)
    ‎The theory of Engel groups plays an important role in group theory since these groups are closely related to the Burnside problems‎. ‎In this survey we consider several classical and novel algorithmic problems for Engel ...
