Workshop:


New perspectives in hyperplane and reflection arrangements


Bochum (Germany)


Monday, February 10, 2014


The intention of this workshop is to provide a forum on new developments in the theory of hyperplane and reflection arrangements. The contributions by international leading experts will concentrate on geometric, combinatorial and computational aspects.
