Günter Rote's Retirement Colloquium

Schedule
14:30–14:59
Refreshments
14:59–15:00
Opening
15:00–15:15
Günter M. Ziegler (FU Berlin)
Welcome Address
15:15–16:00
Andrei Asinowski (Alpen-Adria-Universität Klagenfurt)
Pattern avoidance in rectangulations, permutations, and inversion sequences.
I will present recent structural and enumerative results on pattern-avoiding rectangulations and their connections to permutations, inversion sequences, and lattice paths.
16:00–16:30
Coffee and Cake
16:30–17:15
Stefan Felsner (TU Berlin)
Antipodal pairs and crossing numbers.
We show that minimal counterexamples to the Hill conjecture about the crossing number of the complete graph and a more recent conjecture of Mohar about the crossing number of M2kt do not contain antipodal pairs. The graph Mnt is obtained from the complete graph Kn by removing the edges of a matching of size t. This yields large families of drawings for which the conjectures are true.
17:15–18:00
Tobias Lenz (HTW Berlin)
Günter Rote–A playful retrospect
18:00–18:05
Closing Remarks
18:05–???
Barbecue Party
About Günter Rote

Günter Rote was born in 1960 in Klagenfurt, Austria. He received his PhD under the supervision of Rainer E. Burkard from TU Graz in 1988. Günter Rothe is an expert in computational geometry, and he has coined many colorful German expressions such as “Balde” (treap), “Fegegerade” (sweep line), or “Kanalgitter” (hashtag). Günther has collaborated with generations of researchers in Germany and around the world. He has advised 14 PhD students, many of whom went on to become distinguished scientists.
