CAUTION: The Sender of this email is not from within Dalhousie. Post-proceedings of the??TYPES 2020 ???????? 26th International Conference on Types for Proofs and Programs ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? Open call for papers TYPES is a major forum for the presentation of research on all aspects of type theory and its applications. TYPES 2020 wasn???t held in Turin as planned because of the COVID-19 outbreak. Nonetheless the significant number of submissions and registrations testified the interest for TYPES in our community, motivating us to plan publishing post-proceedings. The post-proceedings volume will be published in LIPIcs, Leibniz International Proceedings in Informatics <http://www.dagstuhl.de/en/publications/lipics>, an open-access series of conference proceedings. Submission to this post-proceedings volume is open to everyone, also to those who did not submit a contribution to 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. We would like to invite all researchers that study and apply type systems to share their results. In particular, we welcome submissions on the following topics: * Foundations of type theory and constructive mathematics; * Homotopy type theory; * 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; * Type theory in linguistics. Important dates: * Paper submission: 19 October 31 October 2020 * Author notification: 18 January 2021 * Final version: ??15 February 2021 * Publication (presumably): end of March 2021 Details: * Papers have to be written in LaTex and adhere to the style requirements of LIPIcs <http://www.dagstuhl.de/en/publications/lipics/instructions-for-authors>. * The recommended length of a paper is 12-15 pages, excluding front-page(s) (authors, affiliation, keywords, abstract, ...), bibliography and an appendix of max 5 pages.
