Property (T) and Kazhdan projections. (2022) [pdf] A proof of the characterisation of Property (T) by the existence of the Kazhdan projection in the full C*-algebra. These notes were written mainly for myself, but I believe they could be useful to anyone trying to understand this proof.
The Haagerup Property and Generalisations. (2022) [pdf] Lecture notes written for a mini-course that never took place. I make them available here in case someone finds them useful/interesting.
