ABSTRACT. In this paper, we introduce the notion of fuzzy costs in a more general context, in
universal algebra by the use of coset terms. We study the structure of fuzzy cosets by applying the
general theory of algebraic fuzzy systems. Fuzzy cosets generated by a fuzzy set are characterized in
di erent ways. It is also proved that the class of fuzzy cosets determined by an element forms an
algebraic closure fuzzy set system. Finally, we give a set of necessary and su cient conditions for a
complete lattice satisfying the infinite meet distributive law. Some equivalent conditions are derived for a fuzzy ideal of an Ockham
algebra A to become a fuzzy kernel ideal. We also obtain the smallest (respectively, ...
alized almost m-ideals, fuzzy almost m-ideals and fuzzy generalized al-
most m-ideals. We present the results illustrating their mutual di erencs,
and similarities. Along these lines, we bring about their examples, ...
