Inductive Freeness of Ziegler's Canonical Multiderivations for Reflection Arrangements

Torsten Hoge, Gerhard Roehrle

Let $A$ be a free hyperplane arrangement. In 1989, Ziegler showed that the restriction $A^{''}$ of $A$ to any hyperplane endowed with the natural multiplicity is then a free multiarra…

Freeness of multi-reflection arrangements via primitive vector fields

Torsten Hoge, Toshiyuki Mano, Gerhard Roehrle +1

In 2002, Terao showed that every reflection multi-arrangement of a real reflection group with constant multiplicity is free by providing a basis of the module of derivations. We fi…
