The next session of LUW (Logica Universalis Webinar) will be Wednesday January 25, 2023 at 4pm CET (Paris-Geneva-Rome) Speaker: Zalán Gyenis, Jagiellonian University, Kraków, Poland Title of the talk: Universal Algebraic Logic - Dedicated to the Unity of Science Abstract: This is the presentation of a book by Hajnal Andréka , Zalán Gyenis, István Németi and Ildikó Sain that gives a comprehensive introduction to Universal Algebraic Logic. The three main themes are (i) universal logic and the question of what logic is, (ii) duality theories between the world of logics and the world of algebra, and (iii) Tarskian algebraic logic proper including algebras of relations of various ranks, cylindric algebras, relation algebras, polyadic algebras and other kinds of algebras of logic. One of the strengths of our approach is that it is directly applicable to a wide range of logics including not only propositional logics but also e.g. classical first order logic and other quantifier logics. Following the Tarskian tradition, besides the connections between logic and algebra, related logical connections with geometry and eventually spacetime geometry leading up to relativity are also part of the perspective of the book. Besides Tarskian algebraizations of logics, category theoretical perspectives are also touched upon. https://link.springer.com/book/10.1007/978-3-031-14887-3 Associate Organization: Studies in Universal Logic, Birkhäuser / Springer-Nature presented by its Publishing Editor: Frida Trotter https://www.springer.com/series/7391 Chair: Razvan Diaconescu Editorial Board SUL Everybody is welcome to attend Register here: https://cassyni.com/s/logica-universalis/seminars/ Jean-Yves Beziau Series Editor Studies in Universal Logic Organizer of the Logica Universalis Webinar http://www.jyb-logic.org/
