Rough V-coexact Sequence in Rough Group

Last modified: 2021-11-19

#### Abstract

The concept of exact sequences has been widely used in ring and module theory. The *U*-exact sequence and the *V*-coexact sequence are generalizations of the exact sequence. Besides it, rough set theory has been implemented in several algebraic structures such as groups, rings, modules, and others. In this research, a rough *V*-coexact sequence will be constructed in the rough group and its characteristics. Furthermore, we will give the relationship between the *V*-coexact sequence in the group and the rough *V*-coexact sequence in the rough group.
