Odd and even derivations, transposed Poisson superalgebra and 3-Lie superalgebra [PDF]

open access: yesProceedings of the Estonian Academy of Sciences
One important example of a transposed Poisson algebra can be constructed by means of a commutative algebra and its derivation. This approach can be extended to superalgebras; that is, one can construct a transposed Poisson superalgebra given a ...

On the range of completely bounded maps

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1978
It is shown that if every bounded linear map from a C*-algebra α to a von Neumann algebra β is completely bounded, then either α is finite-dimensional or β⫅𝒞⊗Mn, where 𝒞 is a commutative von Neumann algebra and Mn is the algebra of n×n complex matrices.

Commutative Twisted Group Algebras [PDF]

open access: yesTransactions of the American Mathematical Society, 1974
A twisted group algebra L 1 ( A , G ; T , α ) {L^1}(A,G;T,\alpha ) is commutative iff A and G are, T is trivial and α \alpha is symmetric: α ( γ , g ) =

TOPOLOGY SPECTRUM OF A KU-ALGEBRA

open access: yesJournal of New Theory, 2015
–The aim of this paper is to study the Zariski topology of a commutative KU-algebra. Firstly, we introduce new concepts of a KU-algebra, such as KU-lattice, involutory ideal and prime ideal and investigate some basic properties of these concepts ...

States and Measures on Hyper BCK-Algebras

open access: yesJournal of Applied Mathematics, 2014
We define the notions of Bosbach states and inf-Bosbach states on a bounded hyper BCK-algebra (H,∘,0,e) and derive some basic properties of them. We construct a quotient hyper BCK-algebra via a regular congruence relation.

Commutativity in operator algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1990
By an ’operator algebra’ we shall mean a subalgebra A \mathcal {A} of the algebra B ( H ) \mathcal {B}(\mathcal {H}) of bounded operators on a Hilbert space H \mathcal {H} , together with the matrix normed structure

Cubic Of Positive Implicative Ideals In KU- Semigroup

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
In this paper, we define a cubic positive implicative-ideal, a cubic implicative-ideal and a cubic commutative-ideal of a semigroup in KU-algebra as a generalization of a fuzzy (positive implicative-ideal, an implicative-ideal and a commutative-ideal ...

Generalized Reduced Mal'tsev Problem on Commutative Subalgebras of $E_6$ Type Chevalley Algebras over a Field

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
In 1905 I.~Shur pointed out the largest dimension of commutative subgroups in the groups $SL(n,\mathbb{C})$ and proved that for $n>3$ such the subgroups are automorphic to each other.

Commutative families in DIM algebra, integrable many-body systems and q, t matrix models

open access: yesJournal of High Energy Physics
We extend our consideration of commutative subalgebras (rays) in different representations of the W 1+∞ algebra to the elliptic Hall algebra (or, equivalently, to the Ding-Iohara-Miki (DIM) algebra U q , t gl ̂ ̂ 1 $$ {U}_{q,t}\left({\hat{\hat{\mathfrak ...

Hyers-Ulam-Rassias stability of Jordan homomorphisms on Banach algebras

open access: yesJournal of Inequalities and Applications, 2005
We prove that a Jordan homomorphism from a Banach algebra into a semisimple commutative Banach algebra is a ring homomorphism. Using a signum effectively, we can give a simple proof of the Hyers-Ulam-Rassias stability of a Jordan homomorphism between ...
