Automophisms of Nil-Triangular Subrings of Algebras Chevalley Type $G_2$ Over Integral Domain. I

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
Let $N\Phi(K)$ be the nil-triangular subalgebra of the Chevalley algebra over an associative commutative ring $K$ with the identity associated with a root system $\Phi$.

Skew Cyclic Codes Over ℤ4 + u4 With Derivation Based on a New Gray Map and Automorphism

open access: yesIEEE Access
This paper investigates the algebraic structure and properties of skew cyclic codes over the finite chain ring $R = \mathbb {Z}_{4} + u\mathbb {Z}_{4}$ , where $u^{2} = 0$ .

An application of the Sakai's theorem to the characterization of H*-algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
The well-known Sakai's theorem, which states that every derivation acting on a von Neumann algebra is inner, is ,used to obtain a new elegant proof of the Saworotnow's characterization theorem for associative H*-algebras via two-sided H*-algebras.

Nil sets defined through generalized skew derivations having a Jordan-like behavior

open access: yesMathematics Open
Let R be a prime ring of characteristic different from [Formula: see text], C its extended centroid, F and G non-zero generalized skew derivations of R, associated with the same automorphism [Formula: see text] of R and [Formula: see text] a fixed ...
