Commutative Generalized B*-Algebras: Functional Calculus and Equivalent Topologies

open access: yes, 2022
In this chapter we introduce a functional calculus for commutative GB*-algebras (Allan), analogue to that of C*-algebras. It will be often used in various results, but also similar line of thoughts can be applied in further generalizations of C*-algebras, like e.g., the so-called locally convex quasi C*-normed algebras. It is also used for exhibiting a

The Stable Rank of Topological Algebras and a Problem of R. G. Swan [PDF]

open access: yes, 1998
Various notions of stable ranks are studied for topological algebras. Some partial answers to R. G. Swan's problem (Have two Banach or good Frechet algebras as in the density theorem in K -theory the same stable rank?) are obtained.

Topological convolution algebras [PDF]

open access: yes, 2012
In this paper we introduce a dual of reflexive Frechet counterpart of Banach algebras of the form ⋃ p ∈ N Φ p ′ (where the Φ p ′ are (dual of) Banach spaces with associated norms ‖ ⋅ ‖ p ), which carry inequalities of the form ‖ a b ‖ p ⩽ A p , q ‖ a ‖ q

On duality theory and pseudodifferential techniques for Colombeau algebras: generalized delta functionals, kernels and wave front sets [PDF]

open access: yes, 2005
Summarizing basic facts from abstract topological modules over Colombeau generalized complex numbers we discuss duality of Colombeau algebras. In particular, we focus on generalized delta functional and operator kernels as elements of dual spaces.

Operator Algebras on Non-Separable Banach Spaces and Applications in Mathematical Physics

open access: yesThermodynamics Research: Open Access
This paper develops a structural and functional framework for operator algebras acting on nonseparable Banach spaces (NSBS). While classical operator algebras—such as 𝐶∗ - and 𝑊∗ -algebras—are traditionally constructed on separable Hilbert spaces, many ...

Second order quantum difference operator of lacunary weak convergence of sequences

open access: yesFilomat
In this article, we introduce the concept of the second-order quantum difference operator and examine its role within the framework of lacunary weak convergence of sequences.
