Restrictions of aspherical arrangements
Nils Amend, Tilman Moeller, Gerhard Roehrle
In this note we present examples of -arrangements which admit a restriction which fails to be . This shows that asphericity is not hereditary among hyperplane arran…
The topology of arrangements of ideal type
Nils Amend, Gerhard Roehrle
In 1962, Fadell and Neuwirth showed that the configuration space of the braid arrangement is aspherical. Having generalized this to many real reflection groups, Brieskorn conjectur…
On the -problem for restrictions of complex reflection arrangements
Nils Amend, Pierre Deligne, Gerhard Roehrle
Let be a complex reflection group, and the set of the mirrors of the complex reflections in . It is known that the complement $X({\mathscr A}(…
Supersolvable restrictions of reflection arrangements
N. Amend, T. Hoge, G. Roehrle
Let A = (A,V) be a complex hyperplane arrangement and let L(A) denote its intersection lattice. The arrangement A is called supersolvable, provided its lattice L(A) is supersolvabl…
On inductively free Restrictions of Reflection Arrangements
Nils Amend, Torsten Hoge, Gerhard Roehrle
Let W be a finite complex reflection group acting on the complex vector space V and let A(W) = (A(W), V) be the associated reflection arrangement. In an earlier paper by the last t…
