Access to the video lectures from 2020

As you may have noticed, the video lectures from last year are no longer available. The reason for this is that we are not allowed to publish video clips without subtitles. Still, since all the essential contents can be read from the slides shown in the clips, the video lectures can be useful even without subtitles. Thus, as a temporary solution, we have decided to make the clips available at an external webserver. Links to the video lectures can be found here. We apologize for the inconvenience the missing subtitles may cause.
