  • Groups which are isomorphic to their subgroups with non-modular subgroup lattice 
    De Falco, M.; Musella, C. (Algebra and Discrete Mathematics, 2006)
    This paper describes the structure of groups G containing proper subgroups with non-modular subgroup lattice and such that all such subgroups are isomorphic to G.
  • Groups whose non-normal subgroups have small commutator subgroup 
    De Falco, M.; de Giovanni, F.; Musella, C. (Algebra and Discrete Mathematics, 2007)
    The structure of groups whose non-normal subgroups have a finite commutator subgroup is investigated. In particular, it is proved that if k is a positive integer and G is a locally graded group in which every non-normal ...
  • Groups with many self-normalizing subgroups 
    M. De Falco; F. de Giovanni; Musella, C. (Algebra and Discrete Mathematics, 2009)
    This paper investigates the structure of groups in which all members of a given relevant set of subgroups are selfnormalizing. In particular, soluble groups in which every nonabelian (or every infinite non-abelian) subgroup ...
