[OWR201416] (2014)  (30 Mar  05 Apr 2014)The purpose of the Arbeitsgemeinschaft was to review old and new phenomenas of rigidity in mathematics. The broad spectrum of such results was covered, such as MargulisZimmer superrigidity, cocyle and character rigidity. 
0804  Buildings: Interactions with Algebra and Geometry
[OWR20083] (2008)  (20 Jan  26 Jan 2008)The focus of the conference was on buildings and their applications. Buildings are combinatorial structures (metric cell complexes) which may be viewed as simultaneous generalizations of trees and projective spaces. There ... 
0834  C*Algebras
[OWR200837] (2008)  (17 Aug  23 Aug 2008)A C*algebra is an involutive Banach algebra $A$ which satisfies the C*condition $\a^*a\=\a\^2$ for all $a\in A$. The theory of C*algebras goes back to work of Murray and von Neumann, who first studied a special ...

Calculating conjugacy classes in Sylow psubgroups of finite Chevalley groups of rank six and seven
[OWP201310] (Mathematisches Forschungsinstitut Oberwolfach, 20130410)Let $G(q)$ be a finite Chevalley group, where $q$ is a power of a good prime $p$, and let $U(q)$ be a Sylow $p$subgroup of $G(q)$. Then a generalized version of a conjecture of Higman asserts that the number $k(U(q))$ of ... 
Cataland: Why the Fuß?
[OWP201901] (Mathematisches Forschungsinstitut Oberwolfach, 20190121)The three main objects in noncrossing Catalan combinatorics associated to a finite Coxeter system are noncrossing partitions, clusters, and sortable elements. The first two of these have known FußCatalan generalizations. ...
