Abstract

Mathematics Physical Sciences Science & Technology
The concepts of delta beta I-lower and delta beta I-upper approximation as a generalization of rough set theory via delta beta I-open sets are introduced and studied. Some of its basic properties with the aid of examples are proven. Furthermore, the established relationships between the rough approximations reported in [2] and our new approximations are examined.
