On coc-r-compact spaces

Raad Aziz Hussain Al-Abdulla; Fadhel Attala Shneef

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2017, Volume 9, Issue 1, Pages 1-11

In this.work, We will study a.new class of popularizer open.sets called.coc-r-open sets and we will study its properties too, also we will study coc-r-compact, I-Compact space and the relationship between them, finally we have to get some results that show the relationship between these spaces through some of the theorems obtained by using coc-r-open sets.

On Coc- Dimension Theory

Raad Aziz Hussain; Wrood Hasan Hweidee

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2016, Volume 8, Issue 1, Pages 5-13

In this paper we introduce and define a new type on coc-dimension theory. The concept of indX,IndX,dimX, for a topological space X have been studied. In this work, these concepts will be extended by using coc-open sets.

On coc-coercive function

Saied A. Johnny; Hashmiya I. Naser

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2016, Volume 8, Issue 1, Pages 50-53

In this paper , we use the concept of coc-closed and coc-compact sets to construct a new type of functions which is coc-coercive function and investigate the properties of this concept.

On s-coc-separation axioms

Hadeel Husham Al-Zubaidi; Raad Aziz Al-Abdulla

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2015, Volume 7, Issue 2, Pages 1-28

In this paper we introduced new type of separation axioms called s-coc-separation axiomsand we introducedtypes of continuous functionsand study the relation among them. We studiedthe definitions of s-coc-separation axioms ,properties and relation among them .
