Nonlinear Mixed Skew Jordan-Type Higher Derivations on ∗-Algebras
AxiomsLet A be a unital ∗-algebra containing a nontrivial projection P. In this paper, we introduce the notion of a nonlinear mixed skew Jordan-type derivation (that is, pnS1,S2,S3,⋯,Sn=S1⋄S2•S3•⋯•Sn, where S⋄K=S*K+K*S and S•K=SK+KS* for all S,K∈A) and show ...

Derivations on Jordan-Banach algebras
, 1996 We establish that all derivations on a semisimple Jordan-Banach algebra are automatically continuous. By showing that "almost all" primitive ideals in the algebra are invariant under a given derivation, the general case is reduced to that of primitive ...

On generalized (?,?)-derivations
, 2002 We generalize the notion of (?,?)-derivation of Nakajima and Bres˜ar. We define the generalized (?,?)-derivations, generalized Jordan (?,?)-derivations, and generalized Lie (?,?)-derivations.

ON CERTAIN IDENTITY RELATED TO JORDAN *-DERIVATIONS
Glasnik matematički, 2015 In this paper we prove the following result. Let H be a real or complex Hilbert space, let L(H) be the algebra of all bounded linear operators on H and let A(H) ⊆ L(H) be a standard operator algebra. Suppose we have an additive mapping D:A(H) → L(H) satisfying the relation D(An)=D(A)A* n-1+AD(An-2)A* +An-1D(A) for all A A(H) and some fixed integer n>1.

Complex Firms, Controversial Outcomes: Global Evidence on ESG Failures and Remedies
Business Strategy and the Environment, EarlyView.ABSTRACT We examine whether business complexity increases firms' exposure to negative environmental, social, and governance (ESG) outcomes, specifically ESG controversies, using a global panel of firms from 37 countries over the period 2002–2021.

Greens in Regulation: Biodiversity Strategy Implementation Across the Golf Industry
Business Strategy and the Environment, EarlyView.ABSTRACT Although much of the business and biodiversity literature focuses on extractive industries, we turn our attention to the golf industry. Golf courses occupy millions of acres globally, yet biodiversity strategy implementation across the golf industry remains understudied.

Jordan Isomorphisms and Jordan Derivations of Prime Rings with characteristic 2
, 2004 In this thesis, we describe the Jordan isomorphisms and Jordan derivations on prime rings of characteristic 2. We prove that every Jordan isomorphism of M_{n}(F),n >= 3 is either an isomorphism or an antiisomorphism if n is odd, and it is not true if n ...

Lie and Jordan ideals in prime rings with derivations
, 1976 In this paper derivations on Lie and Jordan ideals of a prime ring R R are studied. The following results are proved. (i) Let R R be a prime ring of characteristic not 2 2 , and let U U

Greening the Bottom Line: Public Funding for Circular Economy Initiatives and Financial Stability
Business Strategy and the Environment, EarlyView.ABSTRACT Public funding for circular economy (CE) initiatives plays a crucial role in shaping corporate financial performance, yet its effects remain underexplored. Grounded in the resource‐based view (RBV) of the firm, this study investigates the financial impact of CE funding on private firms, using Portugal as a case study. It analyses the financial
