“…Also, there is an equivalence relation defined between T 2 completions. For a T 2 Cauchy space 2 , and the two completions are equivalent, if each of these two completions is greater than or equal to the other. Note that in case of equivalence, h is a unique Cauchy homeomorphism.…”

“…The completion of Cauchy spaces is already well known and familiar to most of us. In fact, since Keller [5] introduced the axiomatic definition of Cauchy spaces a very rich and extensive completion theory has been developed for Cauchy spaces during the last three decades [2,3,7,10,12]. It seems that Cauchy space rather than uniform convergence space is a natural generalization of completion of uniform space.…”
Abstract. A completion of a Cauchy space is obtained without the T 2 restriction on the space. This completion enjoys the universal property as well. The class of all Cauchy spaces with a special class of morphisms called s-maps form a subcategory CHY of CHY. A completion functor is defined for this subcategory. The completion subcategory of CHY turns out to be a bireflective subcategory of CHY . This theory is applied to obtain a characterization of Cauchy spaces which allow regular completion.

“…When (X,ζ) is a T 2 filter space, completion and extension theorems were established in [4] and later a few other classes of completions were constructed in [2,5]. In this section, we will construct non-T 2 completion and non-T 2 weak completion of a filter space and establish some extension theorems.…”

The well-known completions of T 2 Cauchy spaces and T 2 filter spaces are extended to the completions of non-T 2 filter spaces, and a completion functor on the category of all filter spaces is described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
