Lecture - 14:15

Günter Ziegler - Freie Universität Berlin


New proofs for THE BOOK

Abstract:
According to a legend told by Paul Erdős, God maintains a book, called THE BOOK, which contains perfect mathematical proofs. Martin Aigner and I have, some twenty years ago, started to collect examples, and then made some modest suggestions of proofs that might be in THE BOOK. In this lecture, I will try to present some more.



Colloquium - 16:00

Günter Rote - Freie Universität Berlin


Most general position

Abstract:
We want to place n points in the plane in such a way that they are as far as possible from degenerate situations. This can be measured by different criteria involving angles, distances, or areas. There are various deterministic and randomized methods that compete for yielding good constructions, and their analysis leads to number-theoretic questions.
