ZHANGAZINOVA D. M.
Zhangazinova, D. M. Automorphisms of the universal enveloping algebra of a finite-dimensional Zinbiel algebra with zero multiplication [Text] / D. M. Zhangazinova, A. S. Naurazbekova // Қарағанды университетінің хабаршысы. Математика сериясы. - 2023. - № 4 (112). - P. 173-184. - Bibliogr.: p. 180-182 ISSN 2518-7929.
UDC:

Subject headings
- Automorphisms
Annotation
In 2010 A. Naurazbekova, using the methods of GrObner-Shirshov bases, constructed the basis of the universal (multiplicative) enveloping algebra U(A) of A. Using this result, the automorphisms of the universal enveloping algebra of a finite-dimensional Zinbiel algebra with zero multiplication are described
Keywords
Zinbiel (dual Leibniz) algebra, universal (multiplicative) enveloping algebra, basis, automorphism, affine automorphism, Зинбил (дуалды Лейбниц) алгебрасы, автоморфизм
