Roughness in modules by using the notion of reference points

Authors

  • B. Davvaz Department of Mathematics, Yazd University, Yazd, Iran
Abstract:

 module over a ring is a general mathematical concept for many examples of mathematicalobjects that can be added to each other and multiplied by scalar numbers.In this paper, we consider a module over a ring as a universe and by using the notion of reference points, we provide local approximations for  subsets of the universe.

Roughness in G-modules

Rough set theory is a generalisation of classical set theory. It is an effective mathematical approach to deal with vagueness and ambiguity in information systems. Combining this theory with rough algebraic structures is a recent trend in the area of mathematical research. In this paper we consider G -module as the universal set and we introduce the notion of rough G -module with respect to a G...
