Our PhD reading seminar is a more informal, discussion-based seminar where we read through selected papers as a collective. While the seminar is open to everyone, we are proposing "professor-free" sessions to keep the informal tone. Since we read through the papers together, we don't set a fixed agenda for each session, but simply continue with the paper as far as time allows. There will also be an opportuity for informal discussions on questions arising from research.
Due to the ongoing pandemic, we have suspended in-person meetings for this seminar for the remainder of WS 19/20 and SS 20. However, we now informally discuss papers occassionaly via Zoom.
For more information on the seminar please email Josh Males at jmales@math.uni-koeln.de.
We continue WS19/20 by discussing the above paper of Guerzhoy, Kent, and Rolen.
