On a Question of the Theory of Partially Composition Formations
Aleksandr Tsarev, Nikolay Nikolayevich Vorob'ev · Algebra Colloquium · 2014
Let n > 0 and ω be a non-empty set of primes. It is proved that the lattice of all τ-closed n-multiply ω-composition formations is inductive. It gives a positive answer to a question of Skiba asked in 2001 at the Gomel Algebraic Seminar.
