Rough equalities from posets and rough difference orders
In the initial section of this research paper rough equalities from partially ordered approximation spaces are investigated. Special types of rough equalities are characterized via convex and other types of sets. Extension of these to all types of rough equalities is also indicated. Two new theories of "Rough Difference Order" which are often more general and distinct from that of "Rough Orders" are also developed in the last section by the present author.
