A note on “Generalized fuzzy rough approximation operators based on fuzzy coverings”

► Ref. [1] contains some slight flaws. ► We show these flaws by some concrete examples. ► Furthermore, we provide the correct versions of these flaws. In this note, we show by examples that Theorem 5.3, partial proof of Theorem 5.3′, Lemma 5.4 and Remark 5.2 in [1] contain slight flaws and then prov...
