Rashmi Singh, Jayanti Tripathi Pandey, Anuj Kumar Umrao · WSEAS TRANSACTIONS ON MATHEMATICS · 2020
The present paper is devoted to the study of k, t, d −proximity on rough sets from the relation point of view. The operator O0(φ,Α) and O(φ,Α) is defined using the upper approximation and closure operators derived from the relation. The properties of induced operator and their connections are henceforth obtained. Moreover, our approach represents a new generalization of the operator using upper approximation only.
