Third Virtual Workshop
on Double Categories

Selected days from 2nd – 13th of November, 2026

2026 | 2024 | 2022

The goal of the workshop is to bring together researchers to share recent work on double categories and their applications to domains such as computer science, type theory, applied category theory, and higher category theory. The workshop will be open for everyone to attend online, with recordings of the talks being uploaded after the workshop is finished.

The workshop will hopefully be of interest to both those who are new to double categories and want to learn about the fundamental techniques and viewpoints, and also to domain specialists who are interested in technical results and current topics of active research. We also hope that this workshop will create a snapshot of the research area as it currently stands together with directions for future work, as well as provide an invitation to people wanting to know more about the area, or who are wondering if the tools or ideas in double category theory might be useful to their own research.

This year we are accepting proposals for contributed talks (~45 minutes long). Space is limited, but we hope to include as many speakers as possible in the final programme, which will be organised into several sessions across a two-week period. The submission link for proposals is located below.

This workshop is organised by Bryce Clarke and Tim Hosgood.

We are currently accepting submissions for talks at the workshop.

The deadline for applications is Wednesday the 21st of October (anywhere on earth).
