pairwise connectedness in čech fuzzy soft bi-closure spaces

The concept of cech fuzzy soft bi-closure space (čfs bi-csp) (u,l1,l2, s) is initiated and studied by the authors in [6]. the notion of pairwise fuzzy soft separated sets in čfs bi-csp is defined in this study, and various features of this notion are proved. then, we introduce and investigate the concept of connectedness in both čfs bi-csps and its associated fuzzy soft bitopological spaces utilizing the concept of pairwise fuzzy soft separated sets. furthermore, the concept of pairwise feebly connected is introduced, and the relationship between pairwise connected and pairwise feebly connected is discussed. finally, we provide various instances to further explain our findings.
