Webcalled fuzzy open sets. A fuzzy set Kis called fuzzy closed if Kc 2˝. We denote by ˝c the collection of all fuzzy closed sets in this fuzzy topological space. Obviously, we have: (a) c2˝, (b) if K;M2˝ c, then K_M2˝ and (c) if fK j: j2Jg2˝c, then ^fK j: j2Jg2˝c. Example 2.1.2 [6]. Let X = fa;bg. Let Abe a fuzzy set on X de ned as A(a) = 1 ...

WebAn Introduction to Fuzzy Sets - Witold Pedrycz 1998 The concept of fuzzy sets is one of the most fundamental and influential tools in computational intelligence. Fuzzy sets can provide solutions to a broad range of problems of control, pattern classification, reasoning, planning, and computer vision.
