Approximation of involution in multi-Banach algebras: Fixed point technique

AIMS Mathematics, 2021
In this research work, we demonstrate the Hyers-Ulam stability for Cauchy-Jensen functional equation in multi-Banach algebras by the fixed point technique. In fact, we prove that for a function which is approximately Cauchy-Jensen in multi Banach algebra,

ON CLOSED BCH-ALGEBRA WITH RESPECT TO AN ELEMENT OF A BCH-ALGEBRA

Journal of Kufa for Mathematics and Computer, 2011
   In this paper, we define the concepts of a closed ideal with respect to an element of a BCH-algebra and a closed BCH-algebra with respect to an element of BCH-algebra .

Coupled fixed point theorems on C^⋆-algebra valued bipolar metric spaces

AIMS Mathematics, 2022
In the present paper, we introduce the notion of a $ \mathcal{C}^{\star} $-algebra valued bipolar metric space and prove coupled fixed point theorems.

On existence results of Volterra-type integral equations via $ C^* $-algebra-valued $ F $-contractions

AIMS Mathematics, 2023
It is a fact that $ C^* $-algebra-valued metric space is more general and hence the results in this space are proper improvements of their corresponding ideas in standard metric spaces. With this motivation, this paper focuses on introducing the concepts

Finite-dimensional complex manifolds on commutative Banach algebras and continuous families of compact complex manifolds

Complex Manifolds, 2019
Let Γ(M) be the set of all global continuous cross sections of a continuous family M of compact complex manifolds on a compact Hausdorff space X. In this paper, we introduce a C(X)-manifold structure on Γ(M).

An exotic characterization of a commutative H*-algebra

International Journal of Mathematics and Mathematical Sciences, 2000
Commutative H*-algebra is characterized in terms of the property that the orthogonal complement of a right ideal is a left ideal.

Controlled Continuous g-Frames in Hilbert C*-Modules

Moroccan Journal of Pure and Applied Analysis, 2020
Frame Theory has a great revolution in recent years. This Theory have been extended from Hilbert spaces to Hilbert C*-modules. The purpose of this paper is the introduction and the study of the concept of Controlled Continuous g-Frames in Hilbert C ...

Characterizations of *-antiderivable mappings on operator algebras

Open Mathematics, 2022
Let A{\mathcal{A}} be a ∗\ast -algebra, ℳ{\mathcal{ {\mathcal M} }} be a ∗\ast -A{\mathcal{A}}-bimodule, and δ\delta be a linear mapping from A{\mathcal{A}} into ℳ{\mathcal{ {\mathcal M} }}.

On the classification of nonsimple graph C*-algebras [PDF]

, 2009
We prove that a graph C*-algebra with exactly one proper nontrivial ideal is classified up to stable isomorphism by its associated six-term exact sequence in K-theory.
