0714  Arbeitsgemeinschaft: Conformal Field Theory
[OWR200717] (2007)  (01 Apr  07 Apr 2007)The two major approaches to chiral conformal field theory – one based on operator algebras and one based on vertex algebras – both lead to representation categories which are tensor categories and, in the case of rational ...

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. ...
