Abstract :
Rough groups and rough rings have been investigated by Biswas & Nanda [Bull. Polish Acad. Sci. Math. 42 (1994) 251-254], Kuroki and Wang [Inform. Sci. 90 (1996) 203-220] and Davvaz [Inform. Sci. 164 (2004) 147-163], but in which some conclusions do not always hold in general. In this paper, we have revisited rough rings in a uniform and complete form, some new properties of rough rings are obtained, and the modified versions of those conclusions that are improper in Davvaz [Inform. Sci. 164 (2004) 147-163] are modified.
