Zero Triple Product Determined Matrix Algebras

open access: yesJournal of Applied Mathematics, 2012
Let A be an algebra over a commutative unital ring C. We say that A is zero triple product determined if for every C-module X and every trilinear map {⋅,⋅,⋅}, the following holds: if {x,y,z}=0 whenever xyz=0, then there exists a C-linear operator T:A3⟶X ...

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𝒨).

SURJECTIVE QUADRATIC JORDAN ALGEBRAS

open access: yesEurasian Mathematical Journal, 2020
Summary: We introduce the concepts of surjectivity and linear minimality for quadratic Jordan algebras, then we present a partial classification of such algebras of characteristic 2. As a corollary, we obtain that in substance non-trivial minimal quadratic Jordan algebras are fields.

Defining quantumness via the Jordan product

open access: yes, 2013
We propose alternative definitions of classical states and quantumness witnesses by focusing on the algebra of observables of the system. A central role will be assumed by the anticommutator of the observables, namely the Jordan product.

The Study of Maps Completely Preserving *-Jordan Zero Products on Factor von Neumann Algebras

open access: yesJournal of Harbin University of Science and Technology, 2018
In order to characterize the maps completely preserving *Jordan zeroproducts on factor von Neumann algebras, according to the definition of bilateral complete preserving *Jordan zeroproducts and bilateral 2preserving *Jordan zeroproducts, taking a ...

Maximum Entropy and Sufficiency

open access: yes, 2016
The notion of Bregman divergence and sufficiency will be defined on general convex state spaces. It is demonstrated that only spectral sets can have a Bregman divergence that satisfies a sufficiency condition.

Noncommutative matrix Jordan algebras [PDF]

open access: yesTransactions of the American Mathematical Society, 1992
We consider noncommutative degree two Jordan algebras J \mathcal {J} of two by two matrices whose off diagonal entries are from an anticommutative algebra S \mathcal {S} . We give generators and relations for the automorphism group of J \mathcal {J} and determine ...

Half-axes in power associative algebras

open access: yes, 2018
Let $A$ be a commutative, non-associative algebra over a field $\mathbb{F}$ of characteristic $\ne 2$. A half-axis in $A$ is an idempotent $e\in A$ such that $e$ satisfies the Peirce multiplication rules in a Jordan algebra, and, in addition, the $1 ...

Improving child mental health and learning outcomes and reducing stigma and discrimination in conflict setting: findings from a cluster randomized controlled trial of a classroom‐based psychosocial intervention in rural primary schools in Afghanistan

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Conflict and crises have long‐lasting and dramatic consequences on the mental health of children. We aimed to investigate the effectiveness of a psychosocial intervention on child mental health in Afghanistan. Methods A two‐arm cluster‐randomized controlled trial was conducted in 83 rural primary schools within three provinces of Afghanistan.
