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 some locally soluble infinite dimensional linear groups

Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2008)

The author investigates nonabelian locally soluble linear groups of infinite fundamental dimension and of infinite section p-rank all of whose proper nonabelian subgroups of infinite section p-rank are of finite fundamental ...
Radical functors in the category of modules over different rings

Burban, N.; Horbachuk, O. (Algebra and Discrete Mathematics, 2008)

The category G of all left modules over all rings is studied. Necessary and sufficient conditions for a preradical functor on G to be radical are given. Radical functors on essential subcategories of G are investigated.
The generalized dihedral groups Dih(Zn) as groups generated by time-varying automata

Woryna, A. (Algebra and Discrete Mathematics, 2008)

Let Zn be a cubical lattice in the Euclidean space Rn. The generalized dihedral group Dih(Zn) is a topologically discrete group of isometries of Zn generated by translations and reflections in all points from Zn. We ...
