Local And 2-Local Derivations Of Solvable Leibniz Algebras With Null-Filiform Nilradical, Sardorbek Umrzaqov
Local And 2-Local Derivations Of Solvable Leibniz Algebras With Null-Filiform Nilradical, Sardorbek Umrzaqov
Scientific Bulletin. Physical and Mathematical Research
In the works of Ayupov, Khudoyberdiyev and Yusupov proved that the local and 2-local derivation of solvable Leibniz algebras with model nilradical are derivations. Solvable Leibniz algebras with null-filiform nilradical are the partial case of solvable Leibniz algebras with model nilradical. However, the proof in the paper is different from model nilradical case. The derivation is a fundamental notion in mathematics. Derivations play a prominent role in algebra. There are many generalizations of derivations as antiderivation, δ-derivations, ternary derivations and (α,β,γ)-derivations. One of the important generalizations of derivation is local and 2-local derivations. Local derivations defined by Kadison, Larson and …
On Symmetric Higher (U,R)-N-Derivation Of Prime Rings, Anwar Khaleel Faraj, Marwa Hadi Sapur
On Symmetric Higher (U,R)-N-Derivation Of Prime Rings, Anwar Khaleel Faraj, Marwa Hadi Sapur
Al-Qadisiyah Journal of Pure Science
The main aim of this paper is to define the notions of Symmetric higher (U,R)-n-derivation, (U,R) n-derivation, Jordan(U,R)-n-derivation and higher n-derivation of prime ring to generalize Awtar’s theorem of derivation on Lie ideal of prime ring to symmetric higher(U,R)-n-derivation.
Local And 2-Local Derivation On Solvable Leibniz Algebras Whose Nilradical Is A Quasi-Filiform Leibniz Algebra Of Maximum Length, Shavkat Ayupov, Bakhtiyor Yusupov
Local And 2-Local Derivation On Solvable Leibniz Algebras Whose Nilradical Is A Quasi-Filiform Leibniz Algebra Of Maximum Length, Shavkat Ayupov, Bakhtiyor Yusupov
Karakalpak Scientific Journal
We show that any local derivation on the solvable Leibniz algebras whose nilradical is a quasi-filiform Leibniz algebra of maximum length with the maximal dimension of complementary space to the nilradical is a derivation. Moreover, a similar problem concerning 2-local derivations of such algebras is investigated.

Let $\mathcal{A}$ be a unital, complex normed $\ast$-algebra with the identity element $\textbf{e}$ such that the set of all algebraic elements of $\mathcal{A}$ is norm dense in the set of all self-adjoint elements of $\mathcal{A}$ and let $\{D_n\}_{n = 0}^{\infty}$ and $\{\Delta_n\}_{n = 0}^{\infty}$ be sequences of continuous linear mappings on $\mathcal{A}$ satisfying \[ \left\lbrace \begin{array}{c l} D_{n + 1}(p) = \sum_{k = 0}^{n}D_{n - k}(p)D_k(p),\\ \\ \Delta_{n + 1}(p) = \sum_{k = 0}^{n}\Delta_{n - k}(p)D_k(p), \end{array} \right. \] for all projections $p$ of $\mathcal{A}$ and all nonnegative integers $n$. Moreover, suppose that $D_0(p) = D_0(p)^2$ holds for all projections …

It is well known that the automorphism group $Aut(H)$ of the algebra of real quaternions $H$ consists entirely of inner automorphisms $i_{q}:p\rightarrow q\cdot p\cdot q^{-1}$ for invertible $q\in H$ and is isomorphic to the group of rotations $SO(3)$. Hence, $H$ has only inner derivations $D=ad(x),$ $x\in H$. See [4] for derivations of various types of quaternions over the reals. Unlike real quaternions, the algebra $H_{d}$ of dual quaternions has no nontrivial inner derivation. Inspired from almost inner derivations for Lie algebras, which were first introduced in [3] in their study of spectral geometry, we introduce coset invariant derivations for dual …
