How To Talk

If you would like to give a talk, add a line to the above table and enter your talk time, your name and your talk title. In SoSe 2018, the standard time is on Tuesdays, 12.00. In WS 18/19, the standard time will be Wednesday, 14.00. In the following semester, one standard time will be Wednesday, 9.30..

The talk length is 25-45 minutes.

The above table is mostly for coordination purposes and for people who want to look up future talks. In addition, every speaker should announce her/his talk via email to inform those who do not regularly check this page.

Next Semester

We have reserved a room for talks to be scheduled on Wednesdays, 9.30-10!

Non-standard times

The standard talk times are chosen to minimize conflicts. If, however, your talk can not be scheduled at the standard time, you may use the following table at your convenience. This table is for WS18/19! All: Please correct any errors in the table and add missing information to improve the talk scheduling. For example, most of the tutorial times are missing. Underlined entries block room 2050.
