Positive Implicative Soju Ideals in BCK-Algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)
The notion of positive implicative soju ideal in BCK-algebra is introduced, and several properties are investigated. Relations between soju ideal and positive implicative soju ideal are considered, and characterizations ...
Constructing a Hoop Using Rough Filters
(Wydawnictwo Uniwersytetu Łódzkiego, 2022-09-09)
When it comes to making decisions in vague problems, rough is one of the best tools to help analyzers. So based on rough and hoop concepts, two kinds of approximations (Lower and Upper) for filters in hoops are defined, ...
On the Category of EQ-algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2021-01-20)
In this paper, we studied the category of EQ-algebras and showed that it is complete, but it is not cocomplete, in general. We proved that multiplicatively relative EQ-algebras have coequlizers and we calculated coproduct ...
\(n\)-Fold Filters of EQ-Algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2022-10-14)
In this paper, we apply the notion of \(n\)-fold filters to the \(EQ\)-algebras and introduce the concepts of \(n\)-fold pseudo implicative, \(n\)-fold implicative, \(n\)-fold obstinate, \(n\)-fold fantastic prefilters and ...
Falling Shadow Theory with Applications in Hoops
(Wydawnictwo Uniwersytetu Łódzkiego, 2021-01-20)
The falling shadow theory is applied to subhoops and filters in hoops. The notions of falling fuzzy subhoops and falling fuzzy filters in hoops are introduced, and several properties are investigated. Relationship between ...
A General Model of Neutrosophic Ideals in BCK/BCI-algebras Based on Neutrosophic Points
(Wydawnictwo Uniwersytetu Łódzkiego, 2020-08-15)
More general form of (∈, ∈ ∨q)-neutrosophic ideal is introduced, and their properties are investigated. Relations between (∈, ∈)-neutrosophic ideal and (∈, ∈ ∨q(kT ,kI ,kF ))-neutrosophic ideal are discussed. Characterizations ...
Soju Filters in Hoop Algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2020-12-30)
The notions of (implicative) soju filters in a hoop algebra are introduced, and related properties are investigated. Relations between a soju sub-hoop, a soju filter and an implicative soju filter are discussed. Conditions ...
Module Structure on Effect Algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2020-11-04)
In this paper, by considering the notions of effect algebra and product effect algebra, we define the concept of effect module. Then we investigate some properties of effect modules, and we present some examples on them. ...
PC-lattices: A Class of Bounded BCK-algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2018)
In this paper, we define the notion of PC-lattice, as a generalization of finite positive implicative BCK-algebras with condition (S) and bounded commutative BCK-algebras. We investiate some results for Pc-lattices being ...
Roughness of Filters in Equality Algebras
(Wydawnictwo Uniwersytetu Łódzkiego, 2023-01-25)
Rough set theory is an excellent mathematical tool for the analysis of a vague description of actions in decision problems. Now, in this paper by considering the notion of an equality algebra, the notion of the lower and ...
