nLab networks of category theorists

This page collects the various networks and communities, in the largest possible sense, of mathematicians and non-mathematicians whose research is category theory-oriented.

It is by no means a comprehensive list, in strict alphabetic order.

• Applied Category Theory (ACT) – On applied category theory.

• CoACT – the Centre of Australian Category Theory at Macquarie University.

• ItaCa – a network of Italian category theorists. The network organises both a permanent on-line seminar, and a annual in-person meeting. Besides these scientific activities, they are also committed to the popularization of CT on italian soil. In 2021 they hosted on YouTube a full introductory course in italian.

• Math-Phys-Cat (home page) – Mathematical-Physics and Categorification Group, a Brazilian research group on mathematical physics with emphasis on higher category theory and physics.

• TallCats – the Compositional Systems and Methods group at TalTech University, Tallinn, Estonia.

• Topos institute – an “independent scientific institute devoted to fundamental inquiry that shapes the technologies of tomorrow”.

• YaMCATS – the Yorkshire and Midlands Category Theory Seminar, is a category theory research network between the universities of Birmingham, Leeds, Leicester and Sheffield. The network is partially funded by the London Mathematical Society.
