A note on "Resolution of fuzzy relation equations (I) based on Boolean-type implications"
This paper shows, by examples, that Lemma 2.1, Lemma 3.1, Corollary 3.1, Corollary 3.2, Theorem 3.1, Corollary 3.3, Theorem 3.3 and Lemma 4.1 in [Y. Luo, Resolution of fuzzy relation equation (I) based on Boolean-type implications, Comput. Math. Appl. 52 (2006) 421-428] about resolution of fuzzy relation equations based on Boolean-type implications, are false. We also point out that the solution set of Example 5.1 is not right and we give the right solution set of Example 5.1. (c) 2009 Elsevier Ltd. All rights reserved.
