-===== 2022 Session 1 : Directed minors and digraph structure theory =====
-Digraph structure theory has known several exciting developments recently.  We propose to
-learn and work on topics around the directed flat wall theorem.  In particular, there will
-be introductory talks to butterfly minors, directed tree-width, the directed grid-theorem
-and the directed flat wall theorem. We shall also explore links and extensions of these
-(matching theory, tournaments immersion, strong minors).
-The workshop is intended to last one week (five workdays), starting on a Monday with two
-talks, an open-problem session, and the formation of groups. A typical day after Monday
-would have one talk, two coffee breaks and a progress report for half of the
-working groups (plus voluntary interventions in cases of specific news to report). The
-first day will have two talks, plus the open-problem session and formation of the groups.
-One board game evening (e.g. arena).
