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 ...
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 ...
