============================================================= 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).
