  • Some characterisations of groups in which normality is a‎ ‎transitive relation by means of subgroup embedding properties 

    Esteban-Romero, Ramon؛ Vincenzi, Giovanni (University of Isfahan, 2018-06-01)
    ‎In this survey we highlight the relations between some subgroup embedding properties that characterise groups in which normality is a transitive relation in‎ ‎certain universes of groups with some finiteness properties‎.

  • Representations of group rings and groups 

    Hurley, Ted (University of Isfahan, 2018-06-01)
    An isomorphism between the group ring of a finite group and a ring of certain block diagonal matrices is established. It is shown that for any group ring matrix $A$ of $mathbb{C} G$ there exists a matrix $U$ (independent ...

  • On the dimension of the product $[L_2,L_2,L_1]$‎ in free Lie algebras 

    Mansuroğlu, Nil (University of Isfahan, 2018-06-01)
    Let $L$ be a free Lie algebra of rank $rgeq2$ over a field $F$ and let $L_n$ denote the degree $n$ homogeneous component of $L$‎. ‎By using the dimensions of the corresponding homogeneous and fine homogeneous components ...

  • On finite groups with square-free conjugacy class sizes 

    Felipe, Maria-Jose؛ Martinez-Pastor, Ana؛ Ortiz-Sotomayor, Victor-Manuel (University of Isfahan, 2018-06-01)
    We report on fi nite groups having square-free conjugacy class sizes, in particular in the framework of factorised groups.

  • On metacyclic subgroups of finite groups 

    Ballester-Bolinches, Adolfo (University of Isfahan, 2018-06-01)
    ‎The aim of this survey article is to present some structural results about of groups whose Sylow p-subgroups are metacylic (p a prime)‎. ‎A complete characterisation of non-nilpotent groups whose ...

  • Sylow multiplicities in finite groups 

    Levy, Dan (University of Isfahan, 2018-06-01)
    Let $G$ be a finite group and let $mathcal{P}=P_{1},ldots,P_{m}$ be a sequence‎ ‎of Sylow $p_{i}$-subgroups of $G$‎, ‎where $p_{1},ldots,p_{m}$ are the distinct‎ ‎prime divisors of $leftvert Grightvert $‎. ‎The Sylow ...
