Some results on Bipolar Fuzzy Graph

Abstract

<span>In this paper, the notion ofgraph operations</span><span>disjunction and symmetric difference on bipolar fuzzy graphs are defined and it is proved that the new graph is a bipolar graph. Furthermore,the </span><span lang="EN-GB">new concepts</span><span> of bipolar fuzzy graphs calledupperstrong and lower strongbipolar fuzzy graphare introduced and some </span><span lang="EN-GB">related </span><span>properties investigated. Finally, an application of bipolar fuzzy graph is explnaid. </span>
