摘要：
In this paper, separation axioms of topological rough groups are discussed. Two examples are constructed to show that there exist Hausdorff topological rough groups such that they have no regular separation. This answers an open question posed in (Lin et al. in Soft Comput 25: 3441-3453, 2020). We also consider regularity of a strongly topological rough group.
