This page displays the schedule for the Bachelor thesis seminar in topology organized by Markus Hausmann and Stefan Schwede.

The seminar takes place Wednesdays, 10 ct, in seminar room N0.007 in the annex of the Mathematikzentrum, Endenicher Allee 60. Due to the large number of participants there will be two parallel sessions on May 13, July 15 and July 22, the second of which takes place in the seminar room 0.007, also at the Mathematikzentrum. Each talk is 35 minutes long, plus 5 additional minutes for questions.
