Is MIAL (= SLℓ) the weakest substructural core fuzzy logic?
Here we verify the following two: The first is that the system MIAL (= ) can be regarded as the weakest substructural core fuzzy and relevance logic as far as one accepts order property. The second is that MIAL can be weakened by deleting identity. For the first, we first verify that some attempts to provide weak forms of the structural axiom ‘identity’ fail and then provide a diagnose why such attempts fail. We next verify that MIAL and some of its extensions satisfy new strong and weak relevance principles introduced in the paper “R and relevance principle revisited.” For the second, we introduce MAL as a system weaker than MIAL and verify that MAL is a substructural core fuzzy and relevance logic. This implies that MIAL is not the weakest substructural core fuzzy logic if we do not suppose order property.
期刊介绍:
Since its launching in 1978, the journal Fuzzy Sets and Systems has been devoted to the international advancement of the theory and application of fuzzy sets and systems. The theory of fuzzy sets now encompasses a well organized corpus of basic notions including (and not restricted to) aggregation operations, a generalized theory of relations, specific measures of information content, a calculus of fuzzy numbers. Fuzzy sets are also the cornerstone of a non-additive uncertainty theory, namely possibility theory, and of a versatile tool for both linguistic and numerical modeling: fuzzy rule-based systems. Numerous works now combine fuzzy concepts with other scientific disciplines as well as modern technologies.
In mathematics fuzzy sets have triggered new research topics in connection with category theory, topology, algebra, analysis. Fuzzy sets are also part of a recent trend in the study of generalized measures and integrals, and are combined with statistical methods. Furthermore, fuzzy sets have strong logical underpinnings in the tradition of many-valued logics.
