General Program Description: |
The workshop is intented to be a "get-together" of researchers that are interested in some of the topics listed below. There can be some talks, but the emphasis is put mostly on discussions between the invited specialists about some basic problems in their common interest. Most of the time is spent with a small group of people working on problems.
Outline of the Workshop July 2 to July 10: Volume Inequalities July 13 to July 17: Break for the Conference on Convex and Discrete Geometry on the occasion of the retirement of Peter M. Gruber. July 20 to July 30: Global Rigidity, Rigidity and Symmetry Appetizers The following papers put forward a number of open problems for thinking. Károly Bezdek, Tarski's plank problem revisited Robert Connelly, Questions, Conjectures and Remarks on Globally Rigid Tensegrities (updated version) Igors Gorbovickis, Kneser-Poulsen conjecture for large radii Bernd Schulze, Combinatorial and Geometric Rigidity with Symmetry Constraints Talks July 10, Friday
10:00 T. Tarnai, Maximizing the area of the union of five equal circles intersected with a large circle (joint work with Zs. Gáspár, K. Hincz) 11:00 A. Bezdek, Conjectures, related to the Malfatti problem 12:00 Lunch 14:00 I. Gorbovickis, Kneser-Poulsen conjecture for large radii July 20, Monday
