Such a pair of arrangements has an additional property: they admit conjugated equations on the ring of polynomials over Q(√5).engjournal articlehttp://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=353644http://arxiv.org/pdf/math/0307296v2.pdfhttp://www.journals.cambridge.org/open access512.7Line arrangementsBraid monodromy.Geometria algebraica1201.01 Geometría Algebraica
