[Logica-l] Supergroup BLAST!
Dear Cheerful Logicians and Friends of Logic, Welcome back! Happy new year! The first Supergroup BLAST of 2021 lands, as it turns out, on the week of World Logic Day. From the looks of it, this is being quite broadly celebrated. I'll announce a few of the goings-on related to this that folks have asked me to pass on. But if you're wondering whether there's a more local celebration to attend, the answer is probably yes, and I highly encourage you to check in with whoever you think might be organizing it. As our part of the celebration, The Supergroup will be hosting a followup to our Day of Inclusive Logic held over the summer. Details on this event are included below, and will be advertised separately as well. There are four events to announce this week. First, on Tuesday at 08:00 GMT-6, Ekaterina Koubychkina (CLE/Unicamp) is speaking in the Alophis Seminar hosted by Università di Cagliari. The topic is Modal Translations of Many-Valued Logics. Thursday, as mentioned, is World Logic Day, and there are many many events to celebrate this. I will mention only two: first, at 08:30 GMT-6, Hanoch Ben-Yami of Central European University is hosting an event aimed at introducing the Quantified Argument Calculus. Later on Thursday--from 11:00 GMT-6 until 1800 GMT-6--the Supergroup will host our World Logic Day event. Finally, on Friday at 10:00 GMT-6, Fabio Dal Conti Lampert will give the official supergroup talk of the week, on Closure and Contingent Truths. More info below, as usual. I hope to see many of you this week! Supergroup Talk: Speaker: Fabio Dal Conti Lampert Title: Closure and Contingent Truths Time and Date: Friday January 15, 10:00 GMT-6 *Link: * https://ksu.zoom.us/j/91627912542?pwd=b1hjKzJvZ2hENXJ4YzRybWoyMlN4QT09 *Meeting ID:* 916 2791 2542 *Passcode:* closure Abstract: Despite some notorious defenders, most philosophers reject the view that knowledge is closed under (metaphysical) entailment. The main reason for this involves familiar and seemingly absurd consequences this view has concerning necessary truths. I will go over arguments to the end of showing that similar consequences follow with respect to contingent truths: if one’s knowledge is closed under entailment, one can know any true proposition whatsoever. In the end I will apply those arguments to extant views in the philosophy of religion, views which take God to be less than omniscient, and I will argue that such views must impose a further restriction on divine knowledge according to which God’s knowledge fails to be closed under entailment. Talks by Member Groups: *Alophis Seminar* (Università di Cagliari) *Speaker:* Ekaterina Koubychkina (CLE/Unicamp) *Title*: On modal translations of many-valued logics *Time and Date*: Tuesday, January 12th 08:00 (GMT-6) *Link: * https://us02web.zoom.us/j/84714867084?pwd=SVZ4TGREWHExSWp0QXlURktOSkhtZz09 *Meeting ID*: 847 1486 7084 *Passcode*: 114114 *Abstract*: In this talk I will discuss some expressivity results for many-valued and modal logics and survey some translations between these two settings. In particular, two possible strategies for defining these translations will be presented: the linear translations, i.e., translations which preserve the length of the formula, and the exponential ones, which do not preserve the structure of the translated formulas. After discussing the advantages and the drawbacks of each strategy, I will introduce an original exponential translation of each four-valued logic into minimal modal logic, interpreted on neighbourhood semantics. *CEU* *Speaker: *Hanoch Ben-Yami *Title: *Introduction to QUARC: The Quantified Argument Calculus *Time and Date: *Thursday, January 14 08:30 (GMT-6) *Link: *To register and obtain a link to the talk please write to qu...@ceu.edu with the subject line 'Registration Quarc WLD'. *Abstract: * The Quantified Argument Calculus (Quarc) is a new logic system, developed by Hanoch Ben-Yami (Central European University, Vienna) and other philosophers and logicians. Its basic departure from Frege’s logic is in its treatment of quantification: quantifiers are not sentential operators but connect to one‑place predicates to form arguments – quantified arguments – of other predicates. Quarc is closer to natural language in its syntax and the inferences it validates than is the first-order Predicate Calculus, while being at least as strong as the latter. By now, Quarc has been shown to be sound and complete; to contain and validate Aristotle’s logic; it separates quantification from existence, shedding new light on logic’s ontological commitments, and lack thereof; it has been extended to modality, invalidating its analogues of the Barcan formulas; three-valued versions of it have been developed, capturing presupposition failure; additional quantifiers have been incorporated in it, such as ‘most’ and ‘more’; several Quarc proof systems have been developed, including sequent calculi, and its metalogical properties

[Logica-l] LFMTP 2021 - 1st call for papers
= Call for papers Logical Frameworks and Meta-Languages: Theory and Practice LFMTP 2021 Pittsburgh, USA, 16 July 2021 Affiliated with CADE-28 http://lfmtp.org/workshops/2021/ = Abstract submission deadline: 19 April 2021 Paper submission deadline: 26 April 2021 Logical frameworks and meta-languages form a common substrate for representing, implementing and reasoning about a wide variety of deductive systems of interest in logic and computer science. Their design, implementation and their use in reasoning tasks, ranging from the correctness of software to the properties of formal systems, have been the focus of considerable research over the last two decades. This workshop will bring together designers, implementors and practitioners to discuss various aspects impinging on the structure and utility of logical frameworks, including the treatment of variable binding, inductive and co-inductive reasoning techniques and the expressiveness and lucidity of the reasoning process. LFMTP 2021 will provide researchers a forum to present state-of-the-art techniques and discuss progress in areas such as the following: * Encoding and reasoning about the meta-theory of programming languages, logical systems and related formally specified systems. * Theoretical and practical issues concerning the treatment of variable binding, especially the representation of, and reasoning about, datatypes defined from binding signatures. * Logical treatments of inductive and co-inductive definitions and associated reasoning techniques, including inductive types of higher dimension in homotopy type theory * Graphical languages for building proofs, applications in geometry, equational reasoning and category theory. * New theory contributions: canonical and substructural frameworks, contextual frameworks, proof-theoretic foundations supporting binders, functional programming over logical frameworks, homotopy and cubical type theory. * Applications of logical frameworks: proof-carrying architectures, proof exchange and transformation, program refactoring, etc. * Techniques for programming with binders in functional programming languages such as Haskell, OCaml or Agda, and logic programming languages such as lambda Prolog or Alpha-Prolog. LFMTP 2021 will hold a special session in honour of Frank Pfenning. Important Dates Abstract submission deadline: Monday April 19 Submission deadline: Monday April 26 Notification to authors: Monday May 31 Final version due:Monday June 14 Workshop date: Friday July 16 Submission In addition to regular papers, we welcome/encourage the submission of "work in progress" reports, in a broad sense. Those do not need to report fully polished research results, but should be of interest for the community at large. Submitted papers should be in PDF, formatted using the EPTCS style guidelines. The length is restricted to 15 pages for regular papers and 8 pages for "Work in Progress" papers. Submission is via EasyChair: https://easychair.org/conferences/?conf=lfmtp2021 Proceedings A selection of the presented papers will be published online in the Electronic Proceedings in Theoretical Computer Science (EPTCS).
