Domination of vague graphs by using of strong arcs

Sadegh Banitalebi, Rajab Ali Borzooei


The present paper aims to introduce the concepts of adding a strong arc, cobondage set, cobondage number, t-cobondage set, and t-cobondage number in the vague graphs, as well as expressing some of the new segmentation of the aditions of arc and reduce the effect of adding a strong arc on domination parameters in vague graphs. Finally, some of their applications are pinpointed.


Fuzzy graph, Vague graph, additional arc, cobondage numbers.
