International Journal of Engineering and Information Systems (IJEAIS)   Year: 2021 | Volume: 5 | Issue: 12 | Page No.: 82-90 Anti-fuzzy AB-ideals of AB-algebra Dr. Areej Tawfeeq Hameed, Huda Adan Mohammed, Dr. Ahmed Hamzah Abed Abstract: We introduce the notion of anti-fuzzy AB-ideals on AB-algebra, several appropriate examples are provided and some properties are investigated. The image and the inverse image of anti-fuzzy AB-ideals on AB-algebra are defined and how the image and the inverse image of anti-fuzzy AB-ideals on AB-algebra become anti-fuzzy AB-ideals are studied. Moreover, the Cartesian product of anti-fuzzy AB-ideals are given.
