Val Goranko and Graham Leigh NOL seminar organisers Nordic Online Logic Seminar Date Monday, 18 December 2023 at 16:00 CET (UTC+1) on Zoom Speaker Göran Sundholm (Professor of Logic (em.), Leiden University) Title Curry-Howard: a meaning explanation or just another realizability interpretation? Abstract Around 1930 a major paradigm shift occurred in the foundations of mathematics; we may call it the METAMATHEMATICAL TURN. Until then the task of a logician had been to design and explain a full-scale formal language that was adequate for the practice of mathematical analysis in such a way that the axioms and rules of inference of the theory were rendered evident by the explanations. The metamathematical turn changed the status of the formal languages: now they became (meta)mathematical objects of study. We no longer communicate with the aid of the formal systems – we communicate about them. Kleene’s realizability (JSL 1945) gave a metamathematical (re-)interpretation of arithmetic inside arithmetic. Heyting and Kolmogorov (1931-2), on the other hand, had used “proofs” of propositions, respectively “solutions” to problems, in order to explain the meaning of the mathematical language, rather than reinterpret it internally. We now have the choice to view the Curry-Howard isomorphism, say, as a variant of realizability, when it will be an internal mathematical re-interpretation, or to adopt an atavistic, Frege-like, viewpoint and look at the language as being rendered meaningful. This perspective will be used to discuss another paradigm shift, namely that of distinguishing constructivism and intuitionism. The hesitant attitude of Gödel, Kreisel, and Michael Dummett, will be spelled out, and, at the hand of unpublished source material, a likely reason given.

Val Goranko and Graham Leigh NOL seminar organisers -- Nordic Online Logic Seminar Next talk: Monday, February 28, 16.00-17.30 CET (UTC+1), on Zoom (details are provided to the seminar subscribers) Title: Formalization of Mathematics and Dependent Type Theory Speaker: Thierry Coquand, professor in computer science at the University of Gothenburg, Sweden Abstract: The first part will be about representation of mathematics on a computer.Questions that arise there are naturally reminiscent of issues that arise when teaching formal proofs in a basic logic course, e.g. how to deal with free and bound variables, and instantiation rules. As discussed in a 1962 paper of Tarski, these issues are "clearly experienced both in teaching an elementary course in mathematical logic and in formalizing the syntax of predicate logic for some theoretical purposes." I will present two quite different approaches to this problem: one inspired by Tarski's paper (N. Megill, system Metamath) and one using dependent type theory (N.G. de Bruijn). The second part will then try to explain how notations introduced by dependent type theory suggest new insights for old questions coming from Principia Mathematica (extensionality, reducibility axiom) through the notion of universe, introduced by Grothendieck for representing category theory in set theory, and introduced in dependent type theory by P. Martin-Löf.
