  • On a question of A. N. Skiba about totally saturated formations 
    Safonov, V.G. (Algebra and Discrete Mathematics, 2008)
    It is proved that the lattice of τ-closed totally saturated formations of finite groups is distributive. This is a solution of Question 4.2.15 proposed by A. N. Skiba in his monograph "Algebra of Formations" (1997).
  • On τ-closed totally saturated group formations with Boolean sublattices 
    Safonov, V.G. (Algebra and Discrete Mathematics, 2008)
    In the universe of finite groups the description of τ-closed totally saturated formations with Boolean sublattices of τ-closed totally saturated subformations is obtained. Thus, we give a solution of Question 4.3.16 proposed ...
