Dear colleagues, It is my pleasure to invite you to the workshop for Queer and Trans People in Category Theory (QTCat) at the University of Hamburg, Germany, taking place August 12-14 2026. QTCat is a workshop on category theory taken in a broad sense, run by and for queer and trans people. It aims to showcase the research done in this field by the queer and trans community, bringing together people working with category theory in fields such as mathematics, physics, philosophy, computer science and logic, both within and outside of academia, to discuss topics of common interest in a non-competitive environment. Invited speakers include: Jules Hedges Theo Johnson-Freyd Ioannis Markaki Conor Mc Bride Participants are also strongly encouraged to contribute their own talks when registering. Important Dates: Registration open until: 10 May 2026 Workshop: 12 to 14 August 2026 Website: https://qtcat.de Registration: https://www.conferences.uni-hamburg.de/event/684/registrations/828/ We encourage anyone who believes in the relevance and importance of spaces like these to participate.
