Workshop on Homotopy Type Theory/ Univalent Foundations
September 8-9, 2017, Oxford, United Kingdom.
Co-located with FSCD 2017.
Quick info

- Link to the programme
- For speakers: the room is equiped with a computer and projector, as well as with a whiteboard that can be used in parallel with the projector. We recommend you bring your slides on a USB memory stick. If you prefer, HDMI and VGA connectors are available to hook up your laptop to the projector.
Overview
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/Univalent Foundations: from the study of syntax and semantics of type theory to practical formalization in proof assistants based on univalent type theory. As part of the workshop there will be an introductory tutorial intended to make the invited and contributed talks accessible to non-experts.
Format
The workshop will include a tutorial, invited and contributed talks, and possibly a discussion session (depending on scheduling and interest).
For details regarding registration and accommodation see the corresponding FSCD site. FSCD also provides some student funding with application deadline July 21. For all other practical details see the main FSCD site.
