N. Kordi, B.N. Onagh and T. Nozari

Department of Mathematics, Faculty of Sciences, Golestan University, Gorgan, Iran.

Abstract:

In this note, we show that some results in [M.H. Shahzamanian, M. Shirmohammadi and B. Davvaz, Roughness in Cayley graphs, Information Sciences, 180, 2010, 3362-3372] are not correct and present their modified versions.

Keywords:

Cayley graph, Pseudo-Cayley graph, Rough set, Lower and upper approximations.
