Title: Nice Restrictions of Reflection Arrangements
Abstract:
Suppose that \(W\) is a finite, unitary reflection group acting on the complex vector space \(V\). Let \(A = (A(W ), V)\) be its associated hyperplane arrangement. The supersolvable restrictions of these arrangements have recently been classified by Amend, Hoge and Roehrle. Extending this work, we classify all restrictions of reflection arrangements that admit a nice partition, which generalizes the notion of supersolvability.
