Colegas: Nesta quinta-feira 23/04 farei uma palestra remota via Zoom, através do LMU- Munique. A participação é aberta através do ID e senha abaixo.
Na próxima quinta-feira 30 de abril. no mesmo horário a Juliana fará sua palestra também. Gostaria de ver vocês por lá! Abraços, Walter ============================ Remote Talk organized by the Munich Center (Ludwig-Maximilians-Universität München), Thursday April 23th, 2020 Via Zoom https://zoom.us/ Meeting ID: 925-6562-2309 Password: 621422 "The Brazilian Paraconsistency Program and its unfoldings" Walter Carnielli Centre for Logic, Epistemology and the History of Science- CLE University of Campinas-Unicamp walte...@unicamp.br This talk intends to expound the main ideas. and collaborators under the Brazilian Paraconsistency Program (BPP) as founded in the Logics of Formal Inconsistency (LFIs) and in the Logics of Formal Undeterminateness (LFUs). The main academic developments under investigation at BPP are in the areas of: - The foundations of BPP (collaboration with J. Marcos, M.E. Coniglio)) -Philosophy: Contradictions do not need to be ‘real’, they can be understood at the level of information and evidence (collaboration with A. Rodrigues. H. Antunes. B. Mendonça); -Information and reasoning: Paraconsistent logics can be added to our arsenal of rationality, especially when combined with quantitative methods: probability, credal calculi and evidence expanded (collaboration with A. Rodrigues, J. Bueno-Soler); -Foundations of mathematics: new and natural set theories, models for such theories (collaboration with M.E. Coniglio); -New semantics for non-standard logics: possible-translations semantics, society semantics, Fidel structures, twist structures (collaboration with M.E. Coniglio , A. Figallo-Orellano. M. C. Golzio); -New perspectives on Gödel’s Incompleteness: proofs of incompleteness cannot be obtained in the paraconsistent paradigm (experimenting with automatic proof theory, Isabelle) (collaboration with D. Fuenmayor). Two basic questions to be addressed are: 1) What is the nature of contradictions that are accepted in paraconsistent logics? 2) Can paraconsistent logics be really useful? The talk also intends to explain why BPP has gained influence on contemporary computer science, since databases, especially Big Data and the World Wide Web, automatization of complex arguments, etc, are almost inevitably contradictory. ================================ Remote Talk organized by the Munich Center (Ludwig-Maximilians-Universität München), Thursday April 30th, 2020 Via Zoom https://zoom.us/ Meeting ID: to be announced Password: to be announced "Plain fibring combination of polynomic logics" Juliana Bueno-Soler School of Technology University of Campinas juliana.buenoso...@gmail.com The combination of logics is a powerful technique which permits systematic generation of new logic systems. Combinations can be homogeneous or heterogeneous depending whether the systems combined are or not presented by the same proof methods. In this talk I consider the homogeneous technique of Plain Fibring which is dedicated to combining logics defined by matrix semantics. The polynomial ring calculus is a technique which permits to describe a logical system by a set of finite polynomials defined over an appropriate field. This method can be applied to different classes of logics as many-valued logics, modal logics, paraconsistent logics and first order logic. A natural question is whether it is possible to obtain systematically a polynomial ring calculus for the combined systems. In order to answer this question wedefine the method of plain fibring of polynomic logics (polynomial representations of matrix logics), as a companion to the method of combining matrix logics, proposed by M. E. Coniglio and V. Fernandez and fully developed in the book"Analysis and Synthesis of Logics", Canielli et allia, Springer, 2007.(This is a joint workwith Mariana Matulovic.) -- Você está recebendo esta mensagem porque se inscreveu no grupo "LOGICA-L" dos Grupos do Google.
