This paper is devoted to the study of the logical properties of BCK algebras. For formalized BCK algebra theory T, it is proved that T is preserved under submodels and unions of chains; T is neither complete nor model complete, and hence there exist no built-in Skolem function. Moreover, the ultraproduct BCK algebras and the fuzzy ultraproduct of fuzzy subsets of BCK algebras were proposed by using the concept of ultrafilters with corresponding properties of fuzzy ideals discussed. 相似文献

We define an ultraproduct of metric structures based on a maximal probability charge and prove a variant of ?o? theorem for linear metric formulas. We also consider iterated ultraproducts (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) 相似文献

In this paper, we introduce the notion of fuzzy order filters in adjoint semigroups of BCK-algebras. We prove that there is a bijection between the fuzzy ideals of BCK-algebras X and the fuzzy order filters in the adjoint semigroup M(X) of X.AMS Subject Classification (2000) 06F35 03G25 20M10 相似文献

This paper is devoted to thefoldness theory of implicative ideals in BCK-algebras. We use the fuzzy point concept to give some characterizations of fuzzyn-fold implicative ideals and establish some relationships with variousn-fold ideals. We also construct some algorithms for studying the foldness of implicative ideals in BCK-algebras. 相似文献

A direct proof is given of the completeness of ultraproduct spaces when the factor spaces are Banach spaces. The method of proof also shows the completeness of the ultraproduct even when the factor spaces are not complete for many (possibly all) ultrafilters. It is also shown that ultraproduct spaces are separable only when they are finite dimensional. 相似文献
