Category Theory 2023

In July 2023 the International Category Theory Conference will take place at the Université catholique de Louvain.

The last four CT conferences were held at Genova (2021), Edinburgh (2019), Ponta Delgada (2018) and Vancouver (2017).

We have six invited speakers who will each give a 50-minute lecture, and slots for 25-minute contributed talks. We also have the option of presenting a poster. Contributions on all aspects of category theory, pure and applied, are welcome.

The conference will take place entirely on site.
