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