    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 ...

    On finite groups generated by strongly cosubnormal subgroups 
    Ballester Bolinches, Adolfo; Cossey, John; Esteban Romero, Ramón (Elsevier, 2003-01-01)
    [EN] Two subgroups A and B of a group G are cosubnormal if A and B are subnormal in their join <A,B> and are strongly cosubnormal if every subgroup of A is cosubnormal with every subgroup of B. We find necessary and ...

    Sylow permutable subnormal subgroups of finite groups 
    Ballester Bolinches, Adolfo; Esteban Romero, Ramón (Elsevier, 2002-05-15)
    [EN] An extension of the well-known Frobenius criterion of p-nilpotence in groups with modular Sylow p-subgroups is proved in the paper. This result is useful to get information about the classes of groups in which every ...

    Z-permutable subgroups of finite groups 
    Heliel, A.A.; Ballester Bolinches, Adolfo; Esteban Romero, Ramón; Almestady, M.O. (Springer Verlag (Germany), 2016)
    Let Z be a complete set of Sylow subgroups of a finite group G, that is, a set composed of a Sylow p-subgroup of G for each p dividing the order of G. A subgroup H of G is called Z-permutable if H permutes with all members ...
