Examples of Lie and Balinsky-Novikov algebras related to Hamiltonian operators
Topological Algebra and its Applications, 2018 We study algebraic properties of Poisson brackets on non-associative non-commutative algebras, compatible with their multiplicative structure. Special attention is paid to the Poisson brackets of the Lie-Poisson type, related with the special Lie ...

Nonlinear $\ast $-Lie higher derivations of standard operator algebras
, 2018 summary:Let $\mathcal {H}$ be an infinite-dimensional complex Hilbert space and $\mathfrak {A}$~be a standard operator algebra on $\mathcal {H}$ which is closed under the adjoint operation. It is shown that every nonlinear $\ast $-Lie higher derivation $\

Lie ideals and Jordan triple (α,β)-derivations in rings
, 2020 In this paper we prove that on a 2-torsion free semiprime ring R every Jordan triple (alpha, beta)-derivation (resp. generalized Jordan triple (alpha, beta)derivation) on Lie ideal L is an (alpha, beta)-derivation on L (resp.

Generalized derivations as homomorphisms or anti-homomorphisms on Lie ideals
Arab Journal of Mathematical Sciences, 2016 Let R be a prime ring of char(R)≠2, Z the center of R, and L a nonzero Lie ideal of R. If R admits a generalized derivation F associated with a derivation d which acts as a homomorphism or as anti-homomorphism on L, then either d=0 or L⊆Z.

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

On n-Derivations and n-Homomorphisms in Perfect Lie Superalgebras
MathematicsLet n≥2 be a fixed integer. The aim of this paper is to investigate the properties of n-derivations within the framework of perfect Lie superalgebras over a commutative ring R. The main result shows that if the base ring contains 1n−1, and L is a perfect

Characterization of Multiplicative Lie Triple Derivations on Rings
Abstract and Applied Analysis, 2014 Let R be a ring having unit 1. Denote by ZR the center of R. Assume that the characteristic of R is not 2 and there is an idempotent element e∈R such that aRe=0⇒a=0 and aR1-e=0⇒a=0.
