Programme

Each day there are three lectures in the morning and two in the afternoon, each takes 50 minutes.
On Tuesday there is a lecture for general audience on the work of Mariusz Koras (at the University of Warsaw, Banacha 2, room 5440).
On Wednesday there is a conference dinner (details will be given here later).

All abstracts in one pdf.
