    • Commutative Energetic Subsets of BCK-Algebras 

      Jun, Young Bae; Roh, Eun Hwan; Song, Seok Zun (Wydawnictwo Uniwersytetu Łódzkiego, 2016)
      The notions of a C-energetic subset and (anti) permeable C-value in BCK-algebras are introduced, and related properties are investigated. Conditions for an element t in [0, 1] to be an (anti) permeable C-value are provided. ...
    • Grzegorczyk Algebras Revisited 

      Stronkowski, Michał M. (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
      We provide simple algebraic proofs of two important facts, due to Zakharyaschev and Esakia, about Grzegorczyk algebras.
    • Int-Soft Ideals of Pseudo MV-Algebras 

      Jun, Young Bae; Song, Seok-Zun; Bordbar, Hashem (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
      The notion of (implicative) int-soft ideal in a pseudo MV-algebra is introduced, and related properties are investigated. Conditions for a soft set to be an int-soft ideal are provided. Characterizations of (implicative) ...
    • PC-lattices: A Class of Bounded BCK-algebras 

      Shoar, Sadegh Khosravi; Borzooei, Rajab Ali; Moradian, R.; Radfar, Atefe (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 ...
    • Pseudo-BCH Semilattices 

      Walendziak, Andrzej (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
      In this paper we study pseudo-BCH algebras which are semilattices or lattices with respect to the natural relations ≤; we call them pseudo-BCH join-semilattices, pseudo-BCH meet-semilattices and pseudo-BCH lattices, ...
