Based on the theory of a falling shadow which was first formulated by Wang [15], a theoretical approach of the pseudo ideal structure in pseudo d-algebras is established. Several properties are investigated, and relations among a falling pseudo d-subalgebra, a falling pseudo BCK-ideal and a falling pseudo d-ideal are discussed. A characterization of a falling pseudo d-ideal is provided. Conditi...

In this paper, we have enhanced the notion of the direct product of two intuitionistic fuzzy sets to the notion of the generalised direct product oftwo doubt intuitionistic fuzzy subalgebras and two doubt intuitionistic fuzzy H-ideals of two BCK/BCI-algebras using max-min operations. Andwe study some interesting properties of such direct product of doubt intuitionistic fuzzy H-ideal...

In the present manuscript, we introduce concept of a discrete dynamical system (Ⱬ,Ψ) in BCK-algebra where Ⱬ is and Ψ homomorphism from to establish some their related properties. We prove that set all fixed points periodic are BCK-subalgebras. show when subset invariant concerning Ψ. commutative with relative cancellation property ideals Ⱬ. also an S-invariant

In this paper, we introduce the notions of Belluce lattice associated with a bounded $BCK$-algebra and reticulation $BCK$-algebra. To do this, first, define operations $curlywedge ,$ $curlyvee $ $sqcup on $BCK$-algebras study some algebraic properties them. Also, for $A$ Zariski topology Spec(A)$ induced $tau _{A,Max(A)}$ $Max(A)$. We prove $(Max(A),tau_{A,Max(A)})$ is compact topological space...

This paper complements a series of works on implicative verbs such as manage to and fail to. It extends the description of simple implicative verbs to phrasal implicatives as take the time to and waste the chance to. It shows that the implicative signatures of verb-noun collocations depend both on the semantic type of the verb and the semantic type of the noun in a systematic way.

This paper deals with the study of generalizations fuzzy subalgebras and ideals in BCK/BCI-algebras. In fact, notions ∈ , ∨ κ ~ ∗ q -fuz...

We consider the intuitionistic fuzzification of the concept of subalgebras and ideals in BCK-algebras, and investigate some of their properties. We introduce the notion of equivalence relations on the family of all intuitionistic fuzzy ideals of a BCK-algebra and investigate some related properties.
