On Β*c– open set and its properties

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2019, Volume 11, Issue 1, Pages 27-35

In this paper we introduced a new set is said Β*c– open set where we studied and identified its properties and find the relation with other sets and our concluded a new class of the function called Β*c– cont. function, Β*c– open function, Β*c– closed function.

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.

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2016, Volume 8, Issue 1, Pages 78-82

in this research we want to study some of theTopological definitions and theorems by using the concept of σ -algebra. In this paper we define the continuity and separation axioms with respect to this concept .
