## Programme

- A schematic overview can be found here as a pdf-file.
- An `@` after a speaker's name indicates a remote talk. Similarly, a chairman with `@` chairs remotely. “R3.07, R3.28@” is harder to explain: A talk with a speaker in R3.07 is streamed to R3.28 (only necessary when we don't fit into the capacity reduced lecture room R3.07).
- The links to the zoom meeting IDs can be found in the password protected area “Inside Numdiff” to restrict the access to registered participants of NUMDIFF-16.
- A personal folder 📁 contains material related to the talk (slides, preprints or a video recorded at “Pre-Numdiff”). As soon as you put some files in your personal folder (using the edit link communicated by e-mail), we will include the public links here in the programmes (a few hours later, it is not automatic). We will link directly to your folder, i.e., you can update all the files there.
- All times are UTC+2.
