Separation and Epimorphisms in Quasi-Uniform Spaces

Applied Categorical Structures, 2000
It is well known that the category of uniform spaces allows only for relatively few closure operators in the categorical sense. In contrast to this, the present paper shows that the category \textbf{QUnif} of quasi-uniform spaces carries plenty of different closure operators which then are studied comprehensively.

Indentation on a half-infinite one-dimensional hexagonal quasi-crystal space by a rigid flat-ended cylindrical indenter with uniform heat flux or temperature

Mechanics of materials (Print), 2019
The present paper analytically investigates the contact problem of a half-infinite one-dimensional hexagonal quasi-crystal medium punched by a rigid flat-ended cylindrical indenter with uniform heat flux or temperature.

FIBREWISE BICOMPLETE QUASI-UNIFORM SPACES

Far East Journal of Mathematical Sciences (FJMS), 2015
Summary: We introduce the notion of complete quasi-uniform spaces over a base space \(B\) and give some properties of these spaces. We introduce a general method to obtain fibrewise completion of quasi-uniform spaces over \(B\) and give internal descriptions of fibrewise completions for two different types.

On Optimization Problems in Quasi-uniform Spaces

Third International Conference on Natural Computation (ICNC 2007), 2007
This paper is concerned with optimization problems in T0 quasi-uniform spaces. Many optimization problems such as vector optimization, set-valued optimization, are unified in the quasi-uniform space to have a simple expression. Firstly, the proposition that a quasi-uniform space is T0 if and only if the intersection of all entourages of the quasi ...

Cowellpoweredness of Some Categories of Quasi-Uniform Spaces

Applied Categorical Structures, 2018
It is known that there is no example of a subcategory of the category $\mathbf{Unif}$ of uniform spaces that is non-cowellpowered. This paper is concerned with cowellpoweredness of subcategories of $\mathbf{QUnif}$, the category of quasi-uniform spaces, and shows that it has is a lot of cowellpowered and non-cowellpowered subcategories.

*-Compactifications of quasi-uniform spaces

Studia Scientiarum Mathematicarum Hungarica, 2007
By a *-compactification of a T0 quasi-uniform space ( X, U ) we mean a compact T0 quasi-uniform space ( Y, V ) that has a T ( V ∨ V−1 )-dense subspace quasi-isomorphic to ( X, U ). We prove that ( X, U ) has a *-compactification if and only if its T0 biocompletion \documentclass{aastex} \usepackage{amsbsy} \usepackage{amsfonts}

Completeness of Quasi-Uniform and Syntopological Spaces

Journal of the London Mathematical Society, 1994
Because of the unusual gap between the submission date of this paper, July 8, 1989, and its publication date, the paper has already had considerable impact as a preprint. With the retrospective view provided in this way, it is easy to specify the paper's importance: the paper establishes that by suitably modifying certain standard definitions the ...
