    • The lattice of fitting classes which are right extensible by soluble groups 

      Iranzo, M.J.; Lafuente López, Julio Upna; Pérez Monasor, F. (Universidad Autónoma de Barcelona, Departamento de Matemáticas, 2005)   Artículo / Artikulua  OpenAccess
      In this paper we study the set of fitting classes which are right extensible by soluble groups ordered by the inclusion relation. The consideration of the associated lattices gives rise to new fitting classes and it allows ...
    • Los retículos de las clases de Schunck normales y de las clases derivadas 

      Lafuente López, Julio Upna (Real Sociedad Matemática EspañolaCSIC, 1979)   Artículo / Artikulua  OpenAccess
      All groups to be considered are finite. The main result of this paper is the following: the normal Schunck classes compose a complete and distributive lattice antiisomorphic to the lattice composed by the derived classes. ...
