In this article, we introduce the concept of graphs associated with commutative UP-algebra,
which we say is a UP-graph whose vertices are the elements of commutative UP-algebra …

Multi-criteria decision-making (MCDM) approaches have acquired various expansions
under uncertain conditions in current years. The purpose of the current study is to broaden …

In this paper, the notion of closed cubic intuitionistic ideals, cubic intuitionistic p-ideals and
cubic intuitionistic a-ideals in BCI-algebras are introduced, and several related properties …

Based on the theory of fuzzy sets, the notion of fuzzy UP-subalgebras (resp., fuzzy UP-filters,
fuzzy UP-ideals, fuzzy strongly UP-ideals) with thresholds of UP-algebras is introduced …

In this paper, we introduce the notions of left multipliers, right multipliers, anti left multipliers,
and anti right multipliers of UP-algebras, and found that the notion of right multipliers is only …

Fuzzy graphs are very important when we are trying to understand and study complex
systems with uncertain and not exact information. Among different types of fuzzy graphs …

Using the concept of a neutrosophic quadruple number to a fuzzy duplex number, we
introduce the notion of a fuzzy duplex UP-algebra, and investigate some related properties …

In this paper, we apply the notion of bipolar-valued fuzzy set to UP-algebras. We introduce
the notions of bipolar fuzzy UP-subalgebras (resp., bipolar fuzzy UP-filters, bipolar fuzzy UP …

The cubic intuitionistic implicative ideals in BCK-algebras and the relationship between a
cubic intuitionistic subalgebra, a cubic intuitionistic ideal and a cubic intuitionistic implicative …

In this paper, N-fuzzy UP-subalgebras (resp., N-fuzzy UP-filters, N-fuzzy UP-ideals and N-
fuzzy strongly UP-ideals) of UP-algebras are introduced and considered their …
