Student seminar on the combinatorics of permutations (FS17, Fridays, 1pm, room Y27H46)
The assistant for the lecture is Jehanne Dousse (Y27H06). She can answer precise questions on your topic, please contact her by e-mail to set an appointment.
On Tuesday before your presentation: you need to send a report (either typed or with a very clean handwriting) on the material
that you plan to cover. Please send it by e-mail.
