Finite complex reflection arrangements are K(pi,1)
Finite complex reflection arrangements are K(pi,1)
Let V be a finite dimensional complex vector space and W ⊆ GL(V ) be a finite complex reflection group.Let V reg be the complement in V of the reflecting hyperplanes.We prove that V reg is a K(π, 1) space.This was predicted by a classical conjecture, originally stated by Brieskorn …
