Characterizations of derivations and Jordan derivations on Banach algebras
Linear Algebra and its Applications, 2009 AbstractLet A be an algebra and M be an A-bimodule. Let X be in A and δ:A→M be a linear map which satisfies δ(AB)=δ(A)B+Aδ(B) for all A,B∈A with AB=X. It is shown that δ is a Jordan derivation if δ is continuous and X is left (or right) invertible. Also, it is shown that δ is a derivation if X is idempotent such that for M∈M the condition XA(I-X)M=0 ...

On Jordan and Jordan*-generalized derivations in semiprime rings with involution
International Journal of Contemporary Mathematical Sciences, 2007 The purpose of this note is to prove the following result. Let R be a6 −torsion free semiprime *-ring and let G: R−→R be an additive mapping such that G(xyx )= G(x)y ∗ x ∗ + xD(y)x ∗ + xyD(x) holds for all x,y ∈ R and some *-derivations D of R. Then G is a Jordan*generalized derivation.

Some conditions under which Jordan derivations are zero
Journal of Taibah University for Science, 2017 In the current article, we obtain the following results: Let A be an algebra and P be a semi-prime ideal of A. Suppose that d:Aâ(A/P) is a Jordan derivation such that dim{d(a)|aâA}â¤1. If d(P)={0}, then d is zero.

Cross‐Coupling Reactions in Aqueous Micellar Media
European Journal of Organic Chemistry, Accepted Article.Thanks to their ability to efficiently and reliably construct carbon‐carbon and carbon‐heteroatom bonds, cross‐coupling reactions remain at the forefront of chemical research in both academic and industrial settings. However, the growing emphasis on sustainability has exposed the shortcomings of cross‐coupling chemistry in several areas, including the ...
