On ∂-partial-locally compact space [PDF]

open access: yesMathematics and Computational Sciences, 2023
The aim of this paper is to introduce and give preliminary investigation of ∂-partial-locally compact spaces. Locally compactness and ∂-partial-locally compactness are independent of each other.

Locally compact quantum groups [PDF]

open access: yesAnnales Scientifiques de l’École Normale Supérieure, 2000
Summary: We propose a simple definition of a locally compact quantum group in reduced form. By the word `reduced' we mean that we suppose the Haar weight to be faithful. So in fact we define and study an arbitrary locally compact quantum group, represented on the \(L^2\)-space of its Haar weight.

The regular-locally compact coreflection of a stably locally compact locale

open access: yesJournal of Pure and Applied Algebra, 2001
Via the frame of Scott continuous nuclei the author shows that (i) the category of regular locally compact locales and perfect maps appears as a coreflective subcategory of the category of stably locally compact locales and perfect maps; (ii) the category of compact regular locales and continuous maps appears as a coreflective subcategory of the ...

Locally compact, $\omega_1$-compact spaces

open access: yes, 2017
An $\omega_1$-compact space is a space in which every closed discrete subspace is countable. We give various general conditions under which a locally compact, $\omega_1$-compact space is $\sigma$-countably compact, i.e., the union of countably many countably compact spaces. These conditions involve very elementary properties.

Homogeneous Locally Compact Groups

open access: yesJournal of Algebra, 1998
Motivated by their occurrence in topological geometry, the author studies locally compact groups that are homogeneous in the sense that their automorphism group acts transitively on the non-identity elements. The main results say that compact homogeneous groups are precisely the arbitrary powers of cyclic groups of prime order (with product topology ...

Existence Results for Generalized Vector Quasi-Equilibrium Problems in Hadamard Manifolds

open access: yesAxioms, 2022
The purpose of this article was to establish manifold versions of existence theorems for generalized vector quasi-equilibrium problems in locally compact and σ-compact spaces without any continuity assumption.

Locally Compact Rings [PDF]

open access: yesProceedings of the National Academy of Sciences, 1935
As a generalization of theorems of L. Pontryagin, E. R. van Kampen and D. van Dantzig, the authors prove the following theorems: Theorem I: A locally compact and separable (not necessarily associative or commutative) field \(F\) is either a hypercomplex system over the real field or is totally disconnected. Theorem III: A locally compact, separable and

On unconditionally convergent series in topological rings

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
We define a topological ring $R$ to be Hirsch, if for any unconditionally convergent series $\sum_{n\in\omega} x_i$ in $R$ and any neighborhood $U$ of the additive identity $0$ of $R$ there exists a neighborhood $V\subseteq R$ of $0$ such that $\sum_{n ...

Computably Based Locally Compact Spaces [PDF]

open access: yesLogical Methods in Computer Science, 2006
ASD (Abstract Stone Duality) is a re-axiomatisation of general topology in which the topology on a space is treated, not as an infinitary lattice, but as an exponential object of the same category as the original space, with an associated lambda-calculus.

Localized Frames and Compactness [PDF]

open access: yesJournal of Fourier Analysis and Applications, 2015
We introduce the concept of weak-localization for generalized frames and use this concept to define a class of weakly localized operators. This class contains many important operators, including: Short Time Fourier Transform multipliers, Calderon-Toeplitz operators, Toeplitz operators on various functions spaces, Anti-Wick operators, and many others ...
