Local derivations on c*-algebras are derivations

, 2001
Kadison has shown that local derivations from a von Neumann algebra into any dual bimodule are derivations. In this paper we extend this result to local derivations from any C*-algebra into any Banach -bimodule X.

3-Derivations and 3-Automorphisms on Lie Algebras

Mathematics, 2022
In this paper, first we establish the explicit relation between 3-derivations and 3- automorphisms of a Lie algebra using the differential and exponential map.

Jordan ideals and derivations in prime near-rings [PDF]

, 2014
summary:In this paper we investigate $3$-prime near-rings with derivations satisfying certain differential identities on Jordan ideals, and we provide examples to show that the assumed restrictions cannot be ...

Generalized Left Derivations with Identities on Near-Rings

مجلة بغداد للعلوم, 2023
In this paper, new concepts which are called: left derivations and generalized left derivations in nearrings have been defined. Furthermore, the commutativity of the 3-prime near-ring which involves some algebraic identities on generalized left ...

On Implicative Derivations of MTL-Algebras

Axioms, 2022
This paper introduces the implicative derivations and gives some of their characterizations on MTL-algebras. Furthermore, we provide some representation of MTL-algebras by implicative derivations and obtain some representation of Boolean algebra via the ...

What sort of cognitive hypothesis is a derivational theory of grammar?

Catalan Journal of Linguistics, 2019
This paper has two closely related aims. The main aim is to lay out one specific way in which the derivational aspects of a grammatical theory can contribute to the cognitive claims made by that theory, to demonstrate that it is not only a theory’s ...

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...
