ERRATA (for the recorded lectures); last edited 10th May 2022

As I record my lectures, I inevitably find small mistakes in my slides, which I hadn't spotted before using them. You will find below a list of the mistakes I have found so far. These mistakes have already been corrected in the slides themselves (which are also available on the website of the course), but not in the recorded lectures, where it is almost impossible to correct them (without rerecording an entire lecture).
