After several requests, we extend the deadline to 24 November 2019. Open call for papers Post-proceedings of the 25th International Conference on Types for Proofs and Programs TYPES 2019 TYPES is a major forum for the presentation of research on all aspects of type theory and its applications. TYPES 2019 was held 11-14 June in Oslo, Norway. The post-proceedings volume will be published in LIPIcs, Leibniz International Proceedings in Informatics, an open-access series of conference proceedings (http://www.dagstuhl.de/en/publications/lipics). Submission to this post-proceedings volume is open to everyone, also to those who did not participate in the conference. We welcome high-quality descriptions of original work, as well as position papers, overview papers, and system descriptions. Submissions should be written in English, not overlapping with published or simultaneously submitted work to a journal or a conference with archival proceedings. The scope of the post-proceedings is the same as the scope of the conference: the theory and practice of type theory. In particular, we welcome submissions on the following topics: * Foundations of type theory and constructive mathematics; * Homotopy type theory and univalent mathematics; * Applications of type theory; * Dependently typed programming; * Industrial uses of type theory technology; * Meta-theoretic studies of type systems; * Proof assistants and proof technology; * Automation in computer-assisted reasoning; * Links between type theory and functional programming; * Formalizing mathematics using type theory. IMPORTANT DATES * Paper and abstract submission: 24 November 2019 * Author notification: 25 March 2020 DETAILS * Papers have to be formatted with LIPIcs style (currently lipics-v2019.cls) and adhere to the style requirements of LIPIcs: http://www.dagstuhl.de/en/publications/lipics/instructions-for-authors/ * The upper limit for the length of submissions is 20 pages * Papers have to be submitted in pdf through EasyChair: https://easychair.org/conferences/?conf=types2019postproc * Authors have the option to attach to their submission a zip or tgz file containing code (formalized proofs or programs), but reviewers are not obliged to take the attachments into account and they will not be published. * In case of questions, e.g. on the page limit, contact one of the editors.
