Compactness on bipolar soft topological spaces

It is the purpose of this paper to go somewhat deeper into the structure of bipolar soft topological spaces. We shall introduce the concept of bipolar soft compactness. By using bipolar soft sets, this situation it furnishes us a basic tool to investigate the compactness in a more general way. For compactness the hereditary property with respect to bipolar soft closed subsets holds. So, bipolar soft compactness is a good extension. The continuous images of bipolar soft compact sets are bipolar soft compact. If bipolar soft topological space is bipolar soft T₂-space, then it will satisfy a stronger separation axiom which will be called bipolar soft normal space in tis paper. Lately for bipolar soft compactness, the Tychonoff product theorem holds.
