Zurich Colloquium in Mathematics

Titel Coloring Random Cayley Graphs (Achtung: new location!)
Referent:in, Affiliation Prof. Dr. Noga Alon, Tel Aviv University, Israel
Datum, Zeit 16. Oktober 2012, 17:15-18:15
Ort KOL G 217
Abstract The study of random Cayley graphs of finite groups is related to the investigation of Expanders and to problems in Combinatorial Number Theory and in Information Theory. I will discuss this topic, describing the motivation and focusing on the question of estimating the chromatic number of a random Cayley graph of a given group with a prescribed number of generators. The investigation of this problem combines combinatorial, algebraic and probabilistic tools. Several intriguing questions that remain open will be mentioned as well.

Zurich Colloquium in Mathematics

Titel Is Dispersion a Stabilizing or Destabilizing Mechanism?
Referent:in, Affiliation Prof. Dr. Edriss S. Titi, University of California, Irvine & Weizmann-Institut, Israel
Datum, Zeit 27. November 2012, 17:15-18:15
Ort KO2 F 150
Abstract In this talk I will present a unified approach for the effect of fast rotation and dispersion as an averaging mechanism for, on the one hand, regularizing and stabilizing certain evolution equations. On the other hand, I will also present some results on which large dispersion is a destabilizing mechanism for the long-time dynamics of certain dissipative evolution equations.
