    • 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, ...
    • Variable Sharing in Substructural Logics: an Algebraic Characterization 

      Badia, Guillermo (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
      We characterize the non-trivial substructural logics having the variable sharing property as well as its strong version. To this end, we find the algebraic counterparts over varieties of these logical properties.
