(θ1,θ2) - Derivation Pair on Rings

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2022
Ring theory is one of the influential branches of abstract algebra. In this field, many algebraic problems have been considered by mathematical researchers who are working in this field.

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Efficacy and Safety of Subcutaneous Efgartigimod PH20 in Adults With Primary Immune Thrombocytopenia (ADVANCE SC): A Multicenter, Randomized, Double‐Blinded, Placebo‐Controlled, Phase 3 Trial

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Primary autoimmune thrombocytopenia (ITP) is characterized by thrombocytopenia, bleeding, and reduced health‐related quality of life. In the Phase 3 ADVANCE IV study, intravenous efgartigimod induced significant platelet count responses versus placebo in patients with chronic ITP. ADVANCE SC, a Phase 3, multicenter, randomized, double‐blinded,

Lie triple derivation and Lie bi-derivation on quaternion rings

open access: yesMiskolc Mathematical Notes
In this study, we prove the existence of the central Lie bi-derivation for the ring with identity on the quaternion ring. We also describe the triple Lie derivation using the Jordan derivation on the aforementioned ring.

ON JORDAN IDEALS AND JORDAN DERIVATIONS OF PRIME RINGS

open access: yesDemonstratio Mathematica, 2004
A classical result by \textit{I. N. Herstein} [Proc. Am. Math. Soc. 8, 1104-1110 (1958; Zbl 0216.07202)] states that a Jordan derivation of a prime ring of characteristic not 2 is a derivation. The main result of the paper shows that the same is true on Jordan ideals of prime rings that are simultaneously subrings.

Jordan and Jordan higher all-derivable points of some algebras [PDF]

open access: yesLinear and Multilinear Algebra, 2013
In this paper, we characterize Jordan derivable mappings in terms of Peirce decomposition and determine Jordan all-derivable points for some general bimodules. Then we generalize the results to the case of Jordan higher derivable mappings. An immediate application of our main results shows that for a nest $\mathcal{N}$ on a Banach $X$ with the ...

Nonlinear Mixed Jordan Triple $ * $-Derivations on $ * $-Algebras

open access: yesSiberian Mathematical Journal, 2022
Let $\mathcal {A}$ be a unital $\ast$-algebra. For $A, B\in\mathcal{A}$, define by $[A, B]_{*}=AB-BA^{\ast}$ and $A\bullet B=AB+BA^{\ast}$ the new products of $A$ and $B$. In this paper, under some mild conditions on $\mathcal {A}$, it is shown that a map $ :\mathcal {A}\rightarrow \mathcal {A}$ satisfies $ ([A\bullet B, C]_{*})=[ (A)\bullet B, C]_{*

Building Community Amidst the Institutional Whiteness of Graduate Study: Black Joy and Maroon Moves in an Academic Marronage

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT This article reflects on the construction of a supportive community of Black Afro‐diasporic graduate students and their supervisors researching issues relating to race in the field of education in Australia. It draws on the concept of marronage—a term rooted in the fugitive act of becoming a maroon, where enslaved people enacted an escape in ...

Jordan (α,β)-Derivations on Operator Algebras

open access: yesJournal of Function Spaces, 2017
Let A be a CSL subalgebra of a von Neumann algebra acting on a Hilbert space H. It is shown that any Jordan (α,β)-derivation on A is an (α,β)-derivation, where α,β are any automorphisms on A. Moreover, the nth power (α,β)-maps on A are investigated.
