On the Specht property of some varieties of associative rings. (Russian) Zbl 0534.16015
Let $$F={\mathbb{Z}}<X_ 1,X_ 2,...>$$ be the free associative ring on a countable free generating set $$X_ 1,X_ 2,...$$. A fully characteristic (T-ideal) Q of F is called Spechtian if it is finitely generated as a T- ideal and if the T-ideals containing Q satisfy the ascending chain condition. The reviewer and M. V. Volkov have shown that a T-ideal, which is generated by the polynomial $$X^ 2-X^ n$$ ($$n\neq 2)$$, is Spechtian [Algebra Logika 20, 155-164 (1981; Zbl 0497.16006)]. The authors give a short new proof of this result.
