This is a quick post for all of my non-Brasilian colleagues who are interested in learning about the research community here. My student Paulo Vitor Macedo Dias has put together a Brasilian Category Theory website. This is meant to be a repository for all things category theory in Brasil: we want to compile lists of events, researchers, research labs, as well as outreach material and research blogs.
A central goal of the project is to build and maintain a comprehensive, up-to-date list of researchers. This is genuinely important: having a clear picture of who is working with category theory—broadly understood, in any area where it plays a role—helps strengthen the community, makes collaboration easier, and increases the visibility of Brasilian research both locally and internationally. We want this list to include everyone, from established researchers to students, and from pure category theorists to those who use category-theoretic ideas in adjacent fields.
We also strongly encourage Brasilians working abroad to register themselves. The Brasilian category theory community extends well beyond the country’s borders, and making those connections visible is an important part of the project.
If you would like your information to appear on the website, you can follow the simple instructions available on the page. You can register either by making a pull request or simply by sending an email to categoriasbrasil@gmail.com.
In the email, please include:
- Full name or laboratory name
- Institutional affiliation (university, institute, etc.)
- Link to your Lattes CV and/or personal website
- Main research areas in Category Theory
- (Optional) A profile photo or laboratory logo
- (Optional) Any additional information you find relevant
The platform is open to everyone, and contributions are very welcome. In particular, anyone can write a blog post by simply submitting a pull request (see the instructions here: https://categorias-brasil.github.io/blog/como-contribuir/).
We are rather excited about the blog section. One of our goals is to create a lively and accessible stream of posts about current research, expository topics, and connections to other areas. If you are a researcher, consider writing a short post explaining your work, sharing an idea, or giving context to a recent result. It doesn’t have to be long or overly formal: clarity and enthusiasm are far more important.
We would also like to make a special call to undergraduate students. You are warmly encouraged to contribute outreach-style posts that explain concepts from category theory in simple, intuitive language. Writing these kinds of posts is a great way to solidify your own understanding while helping others enter the subject. Even explaining a single definition or example can make a real difference.
Our hope is that this website becomes not just a directory, but a genuine hub for interaction—helping people discover each other’s work, fostering collaborations, and making the Brasilian category theory community more visible internationally.
And if you’re part of the community in any way, add yourself, write something and encourage others to do the same. Let’s build our community together!
Abraços,
Ben
