    A question on partial CAP-subgroups of finite groups 
    Ballester Bolinches, Adolfo; Esteban Romero, Ramón; Li, Yangming (Springer and Science China Press, 2012-05)
    A subgroup H of a finite group G is a partial CAP-subgroup of G if there is a chief series of G such that H either covers or avoids every chief factor of the series. The structural impact of the partial cover and avoidance ...

    On mutually permutable products of finite groups 
    Ballester-Bolinches, A.; Li, Yangming; Pedraza Aguilera, María Carmen; Su, Ning (European Mathematical Society Publishing House, 2018-12-28)
    [EN] The main purpose of this paper is to study mutually permutable products G = AB in which the subgroups of prime order p and cyclic of order 4 (if p = 2) of the largest normal subgroup of G contained in A boolean AND B ...

    On second minimal subgroups of Sylow subgroups of finite groups 
    Ballester Bolinches, Adolfo; Esteban Romero, Ramón; Li, Yangming (Elsevier, 2011-09-15)
    A subgroup H of a finite group G is a partial CAP-subgroup of G if there is a chief series of G such that H either covers or avoids its chief factors. Partial cover and avoidance property has turned out to be very useful ...

    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) ...

    On the supersoluble hypercentre of a finite group 
    Miao, Liyun; Ballester-Bolinches, Adolfo; Esteban Romero, Ramón; Li, Yangming (Springer-Verlag, 2017-12)
    [EN] We give some sufficient conditions for a normal p-subgroup P of a finite group G to have every G-chief factor below it cyclic. The S-permutability of some p-subgroups of O^p(G)plays an important role. Some known results ...
