1. TWO-VALUED WEAK KLEENE LOGICS
Abstract In the literature, Weak Kleene logics are usually taken as three-valued logics. However, Suszko has challenged the main idea of many-valued logic claiming that every logic can be presented in a two-valued fashion. In this paper, we provide two-valued semantics for the Weak Kleene logics and for a number of four-valued subsystems of them. We do the s

2. BOOK REVIEW: CARNIELLI, Walter & MALINOWSKI, Jacek (eds.). Contradictions, from Consistency to Inconsistency (Trends in Logic 47, Springer International Publishing, 2018, VI+322 pages)
Abstract In this review I briefly analyse the main elements of each chapter of the book centred in the general areas of logic, epistemology, philosophy and history of science. Most of them are developed around a fine-grained investigation on the principle of non-contradiction and the concept of consistency, inquired mainly into the broad area of paraconsiste

3. TOWARDS A PHILOSOPHICAL UNDERSTANDING OF THE LOGICS OF FORMAL INCONSISTENCY
Abstract In this paper we present a philosophical motivation for the logics of formal inconsistency , a family of paraconsistent logics whose distinctive feature is that of having resources for expressing the notion of consistency within the object language in such a way that consistency may be logically independent of non-contradiction. We defend the view a

4. Uma nova abordagem para a noção de quase-verdade / A new approach to the concept of quase-truth
Newton da Costa and his collaborators have introduced the notion of quasi-truth by means of partial structures, and for this purpose, they conceived the predicates as ordered triples: the set of tuples which satisfies, does not satisfy and can satisfy or not the predicate, respectively (the latter represents lack of information). This approach provides a con

5. Paraconsisted computation : a logic approach to quantum / Computação paraconsistente : uma abordagem logica a computação quantica
This work provides evidences to view computational complexity as logic-relative, by introducing new models of computation through non-classical logics and by studying their features with respect to computational expressivity and efficiency. From this point of view, we suggest a new way to study the efficiency of quantum computational models consisting in the

6. Logicas da inconsistencia formal quantificadas / Quantified logics of formal inconsistency
This dissertation aims to develop a sound and complete semantics for a class of first-order logics known as Logics of Formal Inconsistency (LFIs). After general explanation about paraconsistent and first-order semantics, a particular LFI, labeled QmbC, will be characterized by means of an axiom system. Then a sound and complete semantics for it will be const

7. "Um provador de teoremas multi-estratégia" / A Multi-Strategy Tableau Prover
Nesta tese apresentamos o projeto e a implementação do KEMS, um provador de teoremas multi-estratégia baseado no método de tablôs KE. Um provador de teoremas multi-estratégia é um provador de teoremas onde podemos variar as estratégias utilizadas sem modificar o núcleo da implementação. Além de multi-estratégia, o KEMS é capaz de provar teorema

8. Analysis of craniometric variables throughout paraconsistent logic neural network / Modelo de análise de variáveis craniométricas através das redes neurais artificiais paraconsistentes
This work shows the development of an unequal craniometric analysis model, which uses Paraconsistent Neural Network, based upon Paraconsistent Logic with two values. Such logical approach has the capability to handle concepts as uncertainness, inconsistency and paracompleteness. It has been used on diverse applications which present such features, constituti

9. Logics of formal inconsistency
According to the classical consistency presupposition, contradictions have an explosive character: Whenever they are present in a theory, anything goes, and no sensible reasoning can thus take place. A logic is paraconsistent if it disallows such presupposition, and allows instead for some inconsistent yet non-trivial theories to make perfect sense. The Logi
