The Crossed Product of Finite Hopf C*-Algebra and C*-Algebra

Mathematics, 2021
Let H be a finite Hopf C*-algebra and A a C*-algebra of finite dimension. In this paper, we focus on the crossed product A⋊H arising from the action of H on A, which is a ∗-algebra.

On the derivations of cyclic Leibniz algebras

Karpatsʹkì Matematičnì Publìkacìï, 2022
Let $L$ be an algebra over a field $F$. Then $L$ is called a left Leibniz algebra, if its multiplication operation $[-,-]$ additionally satisfies the so-called left Leibniz identity: $[[a,b],c]=[a,[b,c]]-[b,[a,c]]$ for all elements $a,b,c\in L$. A linear

Algebra of quantum C $$ \mathcal{C} $$ -polynomials

Journal of High Energy Physics, 2021
Knot polynomials colored with symmetric representations of SL q (N) satisfy difference equations as functions of representation parameter, which look like quantization of classical A $$ \mathcal{A} $$ -polynomials.

On the derivations of Leibniz algebras of low dimension

Доповiдi Нацiональної академiї наук України, 2023
Let L be an algebra over a field F. Then L is called a left Leibniz algebra if its multiplication operations [×, ×] addition- ally satisfy the so-called left Leibniz identity: [[a,b],c] = [a,[b,c]] – [b,[a,c]] for all elements a, b, c Î L. In this paper,

Stability of ¤-derivations on Lie C¤-algebras

JOURNAL OF ADVANCES IN PHYSICS, 2014
In this paper, we investigate the stability and superstability problems for ¤-derivationsassociated with the generalized Jensen type functional equation on Lie C¤-algebras.

Fuzzy Fixed Point Results in Convex C∗-Algebra-Valued Metric Spaces

Journal of Function Spaces, 2022
The purpose of this note is to come up with some new directions in fuzzy fixed point theory. To this effect, notions of a C∗-algebra-valued fuzzy λ-contraction and related concepts in a convex C∗-algebra-valued metric space (C∗-AVMS) are set-up.

Separable injectivity and C*-tensor products

International Journal of Mathematics and Mathematical Sciences, 1991
Let A and B be C*-algebras and let D be a C*-subalgebra of B. We show that if D is separably injective then the triple (A,B,D) verifies the slice map conjecture. As an application, we prove that the minimal C*-tensor product A⊗B is separably injective if

Characterization of Directed Graphs Representing C*-Algebra of Complex Matrices [PDF]

E3S Web of Conferences
Quantum mechanics is a study that plays a major role in determining the biological intelligence of Artificial Intelligence (AI). Point particle systems in quantum mechanics can be explained using C*-Algebra which is called CAR-algebra. There is a special

Unordered Tuples in Quantum Computation [PDF]

Electronic Proceedings in Theoretical Computer Science, 2015
It is well known that the C*-algebra of an ordered pair of qubits is M_2 (x) M_2. What about unordered pairs? We show in detail that M_3 (+) C is the C*-algebra of an unordered pair of qubits. Then we use Schur-Weyl duality to characterize the C*-algebra

On the K-theory of the C*-algebra associated with a one-sided shift space; pp. 272–279 [PDF]

Proceedings of the Estonian Academy of Sciences, 2010
One-sided shift spaces are a special kind of non-invertible topological dynamical system with which one can associate a C*-algebra. We show how to construct the C*-algebra associated with a one-sided shift space as the Cuntz–Pimsner C*-algebra of a C ...
