Caracterización de un C*-álgebra

Pesquimat, 2016
En el presente trabajo optamos por dar una caracterización de un C*-álgebra A arbitraria. Para esto consideramos la construcción de una representación de un C*-álgebra A de un estado sobre el mismo A.

Lie 2-algebra models [PDF]

, 2014
In this paper, we begin the study of zero-dimensional field theories with fields taking values in a semistrict Lie 2-algebra. These theories contain the IKKT matrix model and various M-brane related models as special cases.

Finitely generated weakly monotone C*-algebra [PDF]

We consider the $C^*$-algebra generated by finitely many annihilation operators acting on the weakly monotone Fock space, and we call it weakly monotone $C^*$-algebra.

The Quantum Symmetry in Nonbalanced Hopf Spin Models Determined by a Normal Coideal Subalgebra

Journal of Mathematics, 2021
For a finite-dimensional cocommutative semisimple Hopf C∗-algebra H and a normal coideal ∗-subalgebra H1, we define the nonbalanced quantum double DH1;H as the crossed product of H with H1op^, with respect to the left coadjoint representation of the ...

C∗-algebraic Smale Mean Value Conjecture and Dubinin-Sugawa Dual Mean Value Conjecture

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
We develop C∗-algebraic analogues of two central problems in complex analysis: the Smale Mean Value Conjecture and the Dubinin-Sugawa Dual Mean Value Conjecture.

A Class of BCI-Algebra and Quasi-Hyper BCI-Algebra

Axioms, 2022
In this paper, we study the connection between generalized quasi-left alter BCI-algebra and commutative Clifford semigroup by introducing the concept of an adjoint semigroup. We introduce QM-BCI algebra, in which every element is a quasi-minimal element,

Nonlinear Skew Lie-Type Derivations on ∗-Algebra

, 2023
Let A be a unital ∗-algebra over the complex fields C. For any H1,H2∈A, a product [H1,H2]•=H1H2−H2H1* is called the skew Lie product. In this article, it is shown that if a map ξ : A→A (not necessarily linear) satisfies ξ

C∗-algebraic Gauss-Lucas Theorem and C∗-algebraic Sendov’s Conjecture

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki
Building on a foundational result established by Robertson [Proc. Edinburgh Math. Soc., 1976], we develop a framework for differentiation of maps defined on specific classes of unital commutative C∗-algebras.

ON A REDUCED CROSSED PRODUCT OF A GROUP BY A C*-ALGEBRA. THE CASES OF CONTINUOUS TRACE AND TYPE I REDUCED CROSSED PRODUCT [PDF]

Romanian Journal of Mathematics and Computer Science, 2014
This paper analyzes two special cases of C* -algebras, the cases of universal crossed product and reduced crossed product of a group by a C* -algebra. In the hypothesis that the universal crossed product is a continuous trace C* -algebra or a type I C* -

Functors Induced by Cauchy Extension of C$^ast$-algebras [PDF]

Sahand Communications in Mathematical Analysis, 2019
In this paper, we give three functors $mathfrak{P}$, $[cdot]_K$ and $mathfrak{F}$ on the category of C$^ast$-algebras. The functor $mathfrak{P}$ assigns to each C$^ast$-algebra $mathcal{A}$ a pre-C$^ast$-algebra $mathfrak{P}(mathcal{A})$ with completion $
