Feeble b-Supra Open Soft Sets and the Essential Topological Operators Inspired by Them

In the article at hand, we expand the classes of feeble α-supra open soft sets, feeble semi-supra open soft sets, and feeble pre-supra open soft sets by introducing the class of feeble b-supra open soft sets. This class is defined by b-supra open subsets of parametric supra topological spaces, so it associates the frameworks of supra topologies and soft supra topologies. We study the basic properties of feeble b-supra open soft sets and point out their behaviours under certain kinds of soft functions and the finite Cartesian product spaces. We also reveal the relationships between this class and certain existing classes, with the aid of illustrative examples. Following this line of research, we make use of the class of feeble b-supra open soft sets and b-closed sets to set up some topological operators in soft settings. We investigate the master features of these operators and derive formulas linking them.
