ANNOUNCEMENT AND CALL FOR CONTRIBUTIONS For the FACETS OF REALIZABILITY workshop. https://project.inria.fr/realizability2019 Cachan (Paris), France, 1 - 3 July 2019. We are looking for people who want to present recent work on topics related to realizability. IMPORTANT DATES: Submission deadline: 1st June Workshop: 1st-3rd July BACKGROUND: The goal of the workshop is to bring together researchers interested in realizability or whose research involves applications of realizability. Here, ???realizability??? is to be understood in a very broad sense to foster new ideas from interaction of people working on its different aspects. The main focus will be realizability interpretations, arithmetic, function and categorical realizability and in particular work on the boundary between any of these. An example of a concept that lies at the border between arithmetic and function realizability is the principle of bar induction. INVITED SPEAKER: Paulo Oliva TOPICS: The scope of the workshop includes but is not limited to: - Number realizability - Modified realizability - Function realizability - Computable analysis - Dialectica interpretation - Classical realizability - Synthetic topology - Categorical realizability - Bar induction / bar recursion Short abstracts (at most half a page excluding references) should be sent to the two organizers directly with subject line ???[facets of realizability] abstract???. There will be no formal reviewing but the organizers will select work they consider relevant to the workshop and give notification of accepted abstracts as they arrive. The abstracts will not be published and contributions about submitted or already published work are welcome. the organizers, Valentin Blot & Florian Steinberg [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
