The polyadic algebras that arise from the algebraization of the first-order extensions of a SIC are characterized and a representation theorem is proved. Standard implicational calculi (SIC)’s were considered by H. Rasiowa [19] and include classical and intuitionistic logic and their various weakenings and fragments, the many-valued logics of Post and Lukasiewicz, modal logics that admit the ru...

In this paper, we apply the concept of linear Diophantine fuzzy sets in BCK/BCI-algebras. respect, notions subalgebras and (commutative) ideals are introduced some vital properties discussed. Additionally, characterizations considered. Moreover, associated results for subalgebras, commutative obtained.

Abstract We explored new algebra structures such as ? —algebra, —subalgebra and —ideal in this work. In addition, we study their fundamental characteristics connections with other algebras, d/?/BCK - – subalgebras ideals. Also, some examples to illustrate our notions are given.
