Abstract
Extending earlier work by Sommers and Tymoczko, in 2016, Abe, Barakat, Cuntz, Hoge, and Terao established that each arrangement of ideal type stemming from an ideal in the set of positive roots of a reduced root system is free. Recently, Röhrle showed that a large class of the satisfy the stronger property of inductive freeness and conjectured that this property holds for all In this paper, we confirm this conjecture.
