Roughness in $G$-graphs

Comment.Math.Univ.Carolin. 61,2 (2020) 147-154.

Abstract:$G$-graphs are a type of graphs associated to groups, which were proposed by A.\ Bretto and A.\ Faisant (2005). In this paper, we first give some theorems regarding $G$-graphs. Then we introduce the notion of rough $G$-graphs and investigate some important properties of these graphs.

Keywords: coset; $G$-graph; rough set; group; normal subgroup; lower approximation; upper approximation
