Abstract This paper traces the history of compactness from the original motivating questions through the development of the definition to a characterization of compactness in terms of nets and filters. The goal of the article is to clarify the central concepts of open-cover and sequential compactness, including details that a standard textbook treatment tends to leave out. 
Simple way to prove compactness of closed intervals in simply ordered set with order topology
In this note, we present a simpler way to prove the compactness of the closed intervals in simply ordered set with order topology.
Introduction to Metric and Normed Spaces
In this chapter, we extend the notion of distance and absolute value from the real and complex number systems to more general spaces, in particular, spaces of functions.
General Measure Spaces
TLDR
In this chapter, results obtained for the real line are extended to more general spaces supplied with a measure.
Various Types of Supra Pre-compact and Supra Pre-Lindelöf Spaces
The purpose of this article is to introduce three types of supra compactness and three types of supra Lindelofness via supra topological spaces based on the supra pre-open sets. With the help of
Measure on the Real Line
There are many examples of functions that associate a nonnegative real number or \(+\infty\) with a set. There is, for example, the number of members forming the set. Given a finite probability
The Open Limit Point Compactness
In this paper, we gave a new topological concept and we called it the open limit point compactness.We have proved that each of the compactness, and the limit point compactness is stronger than of the
Open texture clarified
TLDR
‘Open texture’ is the property of concepts or terms that they are not fully defined with regard to unexpected questions, and it is shown that even though it is a ubiquitous phenomenon, there is no consensus on which way to go about defining it.
Compact Sets
Def: A set A is called sequentially compact if. . .
A game theoretical distributed approach for opportunistic caching strategy
TLDR
The content caching strategy decision is defined as an optimization problem, and potential game is used to decide caching strategy based on Nash Equilibrium in a distributed manner, denoted as Game based Opportunistic Caching Strategy (GOCS).

TLDR
The history of a group of important results in general topology is examined to find out if there are any recent trends in this area that can be traced back to the present day.
