Note on ``. ; /-fuzzy ideals of hemiringsʹʹ

In this paper, we show that Theorem 4.17 and Corollary 4.18 coincide with Theorem 4.11 and Corollary 4.12, respectively, in [W. A. Dudek, M. Shabir, M. Irfan Ali, . ; /-fuzzy ideals of hemirings, Comput. Math. Appl. 58 (2009) 310 321]. We discuss more updated results than Theorem 4.17 and Corollary 4.18 in the paper [W. A. Dudek, M. Shabir, M. Irfan Ali, . ; /-fuzzy ideals of hemirings, Comput. Math. Appl. 58 (2009) 310 321].
