A Survey of Unmixed Bipartite Graphs and Very Well-Covered Graphs
Autor: Diyar M. Mohammed, Adil K. Jabbar, Halgwrd M. Darwesh
Publikováno v: JOURNAL OF UNIVERSITY OF BABYLON for Pure and Applied Sciences. :239-247
Many authors investigated unmixed and bipartite graphs. There are many results obtained on these two types of graphs and show that a bipartite graph G satisfies Serre’s condition S2, then G is Cohen-Macaulay. This paper is a survey with some new re

Pre-irresolute Functions in Closure Spaces
Autor: Sarhad Namiq, Halgwrd M. Darwesh
Publikováno v: European Journal of Pure and Applied Mathematics. 12:1082-1095
The preopen sets are used to define pre-open functions, preclosed functions, pre-continuous functions, contra-pre-continuous functions and pre-irresolute functions which are investigated. They are also used to introduce a new type of connectedness an

Some Properties of Preopen Set in Closure Spaces
Autor: Halgwrd M. Darwesh, Sarhad F Nami
Publikováno v: Journal of Garmian University. 5:229-246
Using the concept of preopen set, we introduce and study closure properties of pre-limit points, pre-derived sets, pre-interior and pre-closure of a set, pre-interior points,pre-border, pre-frontier and pre-exterior in closure space. The relations be

On Minimal ʎ bC -Open Sets
Autor: Sarhad Namiq, Halgwrd M. Darwesh
Publikováno v: Journal of Garmian University. 4:43-60
In this paper, we introduce and discuss minimal -open sets in topological spaces. We establish some basic properties of minimal -open. We obtain an application of a theory of minimal -open sets and we defined a -locally finite space

On -Covering Dimension Functions
Autor: Halgwrd M. Darwesh, Alias B. Khalaf
Publikováno v: Journal of Garmian University. 4:42-50
The present paper is devoted to introduce and study a new type of covering dimension function of topological spaces by using -open sets. For this dimension function, some properties, characterizations and relationships with other concepts are found a
