The Bulletin of the Section of Logic (BSL) is a quarterly peer-reviewed journal published with support of the University of Lodz. Its aim is to act as a forum for timely wide dissemination of novel, significant results in logic through rapid publication of papers not exceding 18 pages. The BSL invites especially the contributions dealing directly with logical calculi, their methodology, application and algebraic interpretations.

Papers may be submitted to the Editor-in-Chief or to any of the Collecting Editors.

BRIEF HISTORY In 1972: Ryszard Wójcicki, Head of the Section of Logic of the Polish Academy of Sciences, at that time based in Wrocław, launches the newsletter-journal designed for the exchange of scientific results among members of the Section with their national and international partners and cooperators. Jan Zygmunt was the editor of the first six issues of the journal. 1975: Grzegorz Malinowski takes on the responsibility of the Managing Editor. 1992: The Department of Logic of Łódź University, takes over publication from the Polish Academy of Sciences and changes its publication policy into a regular peer-reviewed journal. Grzegorz Malinowski becomes Editor-in-Chief. 2012: To continue Polish logical tradition the Editors decided retain the name of the journal unchanged.

  • Functional Completeness in CPL via Correspondence Analysis 

    Leszczyńska-Jasion, Dorota; Petrukhin, Yaroslav; Shangin, Vasilyi; Jukiewicz, Marcin (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    Kooi and Tamminga's correspondence analysis is a technique for designing proof systems, mostly, natural deduction and sequent systems. In this paper it is used to generate sequent calculi with invertible rules, whose only ...
  • Erratum to: Congruences and Ideals in a Distributive Lattice with Respect to a Derivation 

    Barzegar, Hasan (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    The present note is an Erratum for the two theorems of the paper "Congruences and ideals in a distributive lattice with respect to a derivation" by M. Sambasiva Rao.
  • Two Infinite Sequences of Pre-Maximal Extensions of the Relevant Logic E 

    Typańska-Czajka, Lidia (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    The only maximal extension of the logic of relevant entailment E is the classical logic CL. A logic L ⊆ [E,CL] called pre-maximal if and only if L is a coatom in the interval [E,CL]. We present two denumerable infinite ...
  • A Modified Subformula Property for the Modal Logic S4.2 

    Takano, Mitio (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    The modal logic S4.2 is S4 with the additional axiom ◊□A ⊃ □◊A. In this article, the sequent calculus GS4.2 for this logic is presented, and by imposing an appropriate restriction on the application of the cut-rule, it is ...
  • Positive Implicative Soju Ideals in BCK-Algebras 

    Xin, Xiao Long; Borzooei, Rajab Ali; Jun, Young Bae (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 ...
  • Full Cut Elimination and Interpolation for Intuitionistic Logic with Existence Predicate 

    Maffezioli, Paolo; Orlandelli, Eugenio (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    In previous work by Baaz and Iemhoff, a Gentzen calculus for intuitionistic logic with existence predicate is presented that satisfies partial cut elimination and Craig's interpolation property; it is also conjectured that ...
  • Semi-Heyting Algebras and Identities of Associative Type 

    Cornejo, Juan M.; Sankappanavar, Hanamantagouda P. (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    An algebra A = ⟨A, ∨, ∧, →, 0, 1⟩ is a semi-Heyting algebra if ⟨A, ∨, ∧, 0, 1⟩ is a bounded lattice, and it satisfies the identities: x ∧ (x → y) ≈ x ∧ y, x ∧ (y → z) ≈ x ∧ [(x ∧ y) → (x ∧ z)], and x → x ≈ 1. SH denotes ...
  • A Binary Quantifier for Definite Descriptions in Intuitionist Negative Free Logic: Natural Deduction and Normalisation 

    Kürbis, Nils (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    This paper presents a way of formalising definite descriptions with a binary quantifier ℩, where ℩x[F, G] is read as `The F is G'. Introduction and elimination rules for ℩ in a system of intuitionist negative free logic ...
  • The Method of Socratic Proofs Meets Correspondence Analysis 

    Leszczyńska-Jasion, Dorota; Petrukhin, Yaroslav; Shangin, Vasilyi (Wydawnictwo Uniwersytetu Łódzkiego, 2019)
    The goal of this paper is to propose correspondence analysis as a technique for generating the so-called erotetic (i.e. pertaining to the logic of questions) calculi which constitute the method of Socratic proofs by Andrzej ...
  • On Injective MV-Modules 

    Borzooei, Rajabali A.; Goraghani, S. Saidi (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
    In this paper, by considering the notion of MV-module, which is the structure that naturally correspond to lu-modules over lu-rings, we study injective MV-modules and we investigate some conditions for constructing injective ...
  • Rule-Generation Theorem and its Applications 

    Indrzejczak, Andrzej (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
    In several applications of sequent calculi going beyond pure logic, an introduction of suitably defined rules seems to be more profitable than addition of extra axiomatic sequents. A program of formalization of mathematical ...
  • On the Definability of Leśniewski’s Copula ‘is’ in Some Ontology-Like Theories 

    Łyczak, Marcin; Pietruszczak, Andrzej (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
    We formulate a certain subtheory of Ishimoto’s [1] quantifier-free fragment of Leśniewski’s ontology, and show that Ishimoto’s theory can be reconstructed in it. Using an epimorphism theorem we prove that our theory is ...
  • Labeled Sequent Calculus for Orthologic 

    Kawano, Tomoaki (Wydawnictwo Uniwersytetu Łódzkiego, 2018)

    Manzano, María; Moreno, Manuel Crescencio (Wydawnictwo Uniwersytetu Łódzkiego, 2018)
