On the website of the Berkeley mathematics department there is mention (see this) of a colloquium held on november 5, 2020 (by Zoom) whose speaker was Shinichi Mochizuki, with a talk titled "Classical Roots of Inter-universal Teichmüller Theory". The corresponding slides seem to be online (see this). Here are my factual questions:
- did this event really occur ?
- if yes to 1, how was the speaker introduced ?
- if yes to 1, do the slides reflect all that was said, or were there other comments, and if so what ?
