CAUTION: The Sender of this email is not from within Dalhousie. This is the Second Call for Contributions for the (Virtual) Workshop on Homotopy Type Theory and Univalent Foundations July 17-18, 2021, The Internet @ Buenos Aires, Argentina https://hott-uf.github.io/2021/ Co-located with FSCD 2021 https://fscd2021.dc.uba.ar/ Abstract submission deadline: May 25, 2021 Homotopy Type Theory is a young area of logic, combining ideas from several established fields: the use of dependent type theory as a foundation for mathematics, inspired by ideas and tools from abstract homotopy theory. Univalent Foundations are foundations of mathematics based on the homotopical interpretation of type theory. The goal of this workshop is to bring together researchers interested in all aspects of Homotopy Type Theory and Univalent Foundations: from the study of syntax and semantics of type theory to practical formalization in proof assistants based on univalent type theory. # Invited talks * Evan Cavallo (Carnegie Mellon University) * Peter LeFanu Lumsdaine (Stockholm University) * Anja Petkovic (University of Ljubljana) * Matthew Weaver (Princeton University) # Submissions * Abstract submission deadline: May 25, 2021 * Author notification: mid-June 2021 Submissions should consist of a title and an abstract, in pdf format, of no more than 2 pages, submitted via http://easychair.org/conferences/?conf=hottuf2021 Considering the broad background of the expected audience, we encourage authors to include information of pedagogical value in their abstract, such as motivation and context of their work. # Program committee * Benedikt Ahrens (University of Birmingham) * Carlo Angiuli (Carnegie Mellon University) * Paolo Capriotti (Technische Universität Darmstadt) * Floris van Doorn (University of Pittsburgh) * Favonia (University of Minnesota) * Eric Finster (University of Cambridge) * Chris Kapulkin (University of Western Ontario) * Paige Randall North (University of Pennsylvania) * Emily Riehl (Johns Hopkins University) * Christian Sattler (Chalmers University of Technology) * Andrew Swan (Carnegie Mellon University) # Organizers * Benedikt Ahrens (University of Birmingham) * Chris Kapulkin (University of Western Ontario) [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
