The Topological Universe Of Locally Precompact Semiuniform Convergence Spaces

open access: yes, 1996
. The importance of local precompactness has become apparent in theorems of the Ascoli type proved by Bentley and Herrlich [3] in the realm of filter spaces as well as by Wyler [14] in the realm of uniform limit spaces.

SOME PROPERTIES OF J -HAUSDORFF, J -REGULAR AND J -NORMAL SPACES

open access: yes, 2018
In this paper we present new properties about the J - Hausdorff, J -regular and J -normal spaces, introduced recently by Suriyakala-Vembu. Additionally we introduce the J -Urysohn spaces, an intermediate concept between the Urysohn spaces and the J -

Convenient Topology

open access: yes, 1997
. A new viewpoint of Topology, summarized under the name Convenient Topology, is considered in such a way that the structural deficiencies of topological and uniform spaces are remidied. This does not mean that these spaces are superfluous.

Дна бележка върху квази-линдельофовите пространства

open access: yes, 2012
Петра Г. Стайнова - Квази-линдельофовите пространства са въведени от Архангелски като усилване на слабо-линдельофовите. В тази статия се разглеждат няколко свойства на квази-линдельофовите пространства и се правят сравнения със съответни ре- зултати за ...

A Boolean Model of Ultrafilters

open access: yes, 2007
We introduce the notion of Boolean measure algebra. It can be described shortly using some standard notations and terminology. If B is any Boolean algebra, let B N denote the algebra of sequences (xn); xn 2 B: Let us write pk 2 B N the sequence such ...
