    A class of generalised finite T-groups 
    Ballester-Bolinches, A; Feldman ., A.D; Pedraza Aguilera, María Carmen; Ragland., M.F (Elsevier, 2011-05)
    Let F be a formation (of finite groups) containing all nilpotent groups such that any normal subgroup of any T-group in F and any subgroup of any soluble T-group in F belongs to F. A subgroup M of a finite group G is said ...

    Algorithms for permutability in finite groups 
    Adolfo Ballester-Bolinches; Cosme-Llópez, Enric; Esteban Romero, Ramón (Springer Verlag (Germany), 2013-08)
    In this paper we describe some algorithms to identify permutable and Sylow-permutable subgroups of finite groups, Dedekind and Iwasawa finite groups, and finite T-groups (groups in which normality is transitive), PT-groups ...

    Groups whose primary subgroups are normal sensitive 
    Ballester-Bolinches, Adolfo; Kurdachenko, Leonid A.; Otal, Javier; Pedraza Aguilera, Tatiana (Springer Verlag (Germany), 2014-10)
    A subgroup of a group is said to be normal sensitive in if for every normal subgroup of . In this paper we study locally finite groups whose -subgroups are normal sensitive. We show the connection between these groups and ...

    On generalised FC-groups in which normality is a transitive relation 
    Esteban Romero, Ramón; Vincenzi, G. (Cambridge University Press (CUP), 2016-04)
    We extend to soluble FC∗ -groups, the class of generalised FC-groups introduced in [F. de Giovanni, A. Russo, G. Vincenzi, Groups with restricted conjugacy classes , Serdica Math. J. 28(3) (2002), 241 254], the ...

    On self-normalizing subgroups of finite groups 
    Ballester Bolinches, Adolfo; Esteban Romero, Ramón; Li, Yangming (Walter de Gruyter, 2010-01)
    [EN] The aim of this paper is to characterise the classes of groups in which every subnormal subgroup is normal, permutable, or S-permutable by the embedding of the subgroups (respectively, subgroups of prime power order) ...
