A nonhausdorff model for the complement of a complexified arrangement
arXiv:math/0507378
Abstract
Given a hyperplane arrangement A in a real vector space, we introduce a real algebraic prevariety Z(A), and exhibit the complement of the complexification of A as the total space of an affine bundle with fibers modeled on the dual of the ambient vector space.
