Nonlinear Jordan Derivations of Triangular Algebras [PDF]

open access: yesarXiv, 2012
In this paper we prove that any nonlinear Jordan derivation on triangular algebras is an additive derivation. As a byproduct, we obtain that any nonlinear Jordan derivation on nest algebras over infinite dimensional Hilbert spaces is inner.

JORDAN TRIPLE SYSTEMS WITH COMPLETELY REDUCIBLE DERIVATION OR STRUCTURE ALGEBRAS

open access: yes, 1984
We prove that a finite-dimensional Jordan triple system over a field k of characteristic zero has a completely reducible structure algebra iff it is a direct sum of a trivial and a semisimple ideal.

Circular Economy Outcomes in Banks: The Role of Environmental Strategy, Women, and the Sustainability Committee

open access: yesBusiness Strategy and the Environment, Volume 34, Issue 4, Page 4227-4251, May 2025.
ABSTRACT The study investigates how environmental strategies, board gender diversity, and CSR committees affect the circular economy performance in the banking sector. For the first time, we focus on three specific reduction goals: GHG emission reduction, e‐waste reduction, and offering products to reduce the negative environmental impact.

Remarks on Jordan derivations over matrix algebras [PDF]

open access: yesarXiv, 2018
Let C be a commutative ring with unity. In this article, we show that every Jordan derivation over an upper triangular matrix algebra T_n(C) is an inner derivation. Further, we extend the result for Jordan derivation on full matrix algebra M_n(C).

Gender Diversity Leadership and ESG Performance: The Influence of Women on Boards and in Management

open access: yesBusiness Strategy and the Environment, Volume 34, Issue 4, Page 5075-5094, May 2025.
ABSTRACT In recent years, there has been a growing interest among companies and regulatory bodies in adhering to environmental, social, and governance (ESG) standards, alongside an increased involvement of women in organizational decision‐making processes.

A note on derivations and Jordan ideals of prime rings

open access: yesAIMS Mathematics, 2017
Let F : R → R be a generalized derivation of a 2-torsion free prime ring R together witha derivation d: In this paper, we show that a nonzero Jordan ideal J of R contains a nonzero ideal ofR.

σ-derivations on generalized matrix algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
Let 𝒭 be a commutative ring with unity, 𝒜, 𝒝 be 𝒭-algebras, 𝒨 be (𝒜, 𝒝)-bimodule and 𝒩 be (𝒝, 𝒜)-bimodule. The 𝒭-algebra 𝒢 = 𝒢(𝒜, 𝒨, 𝒩, 𝒝) is a generalized matrix algebra defined by the Morita context (𝒜, 𝒝, 𝒨, 𝒩, ξ𝒨𝒩, Ω𝒩𝒨).

Characterizations of derivations and Jordan derivations on Banach algebras

open access: yesLinear 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 ...

Walking and talking for well‐being: Exploring the effectiveness of walk and talk therapy

open access: yesCounselling and Psychotherapy Research, Volume 25, Issue 2, June 2025.
Abstract Despite the rising trend of integrating nature and movement into talking therapy, the extent of empirical support remains limited. This study explored the effects of a walk and talk intervention on adult mood and well‐being using a multiple baseline design with pre, post and follow‐up assessments.
