WebProperties of Fuzzy Relations commutativity, associativity, distributivity, involution, idempotency and De Morgan’s principles all hold for fuzzy relations. the null relation, O, and the complete relation, E, are analogous to the null set and the whole set in set-theoretic form. excluded middle axioms doesn’t hold. WebThe role of symmetry in ring theory is universally recognized. The most directly definable universal relation in a symmetric set theory is isomorphism. This article develops a certain structure of bipolar fuzzy subrings, including bipolar fuzzy quotient ring, bipolar fuzzy ring homomorphism, and bipolar fuzzy ring isomorphism.

WebWith fuzzy set theory, one obtains a logic in which statements may be true or false to di erent degrees rather than the bivalent situation of being true or false; consequently, certain laws of bivalent logic do not hold, e.g. the law of the excluded middle and the law of contradiction. This results in an enriched scienti c methodology.
