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.
