Mathematical Logic
Research interests
- Category theory
- Higher category theory
- Topos theory
- Theory of (higher-type) computation
- Type theory
- Proof formalisation
- Proof theory
Every second Wednesday of the month, we get together for a Typical Lunch with people from the maths and CS departments that are interested in type theory and related subjects. If you are interested in joining these informal gatherings, please contact Johan Commelin or Paige North for details about the exact time and location.
