Invertible algebras satisfying associative identities with functional variables
Abstract
In this paper, the Belousov theorem on linearity of invertible algebras with the Schauffler ∀∃(∀)∀∃(∀)-identity is extended over the other ∀∃(∀)∀∃(∀)-identities of associativity. As a consequence, we obtain the equivalency of the considered ∀∃(∀)∀∃(∀)-identities of associativity and nontrivial hyperidentities of associativity in systems of groups. For the considered formulas, we prove the Schauffler-type theorems, too.
