Real line arrangements and fundamental groups
Let A be a real line arrangement in P(R), and let AC be its complexification. Let CC be the complement P (C) \ ⋃ AC. Let G be the Galois group of C/R. We construct a G-equivariant 2-dimensional strong deformation retract of CC. As an application, we give an explicit presentation of the orbifold fundamental group π1(CC//G), and deduce from it an explicit presentation of the ordinary fundamental ...
متن کاملTopology and combinatorics of real line arrangements
We prove the existence of complexified real arrangements with the same combinatorics but different embeddings in P. Such pair of arrangements has an additional property: they admit conjugated equations on the ring of polynomials over Q( √ 5).
متن کاملStraight Line Arrangements in the Real Projective Plane
Let A be an arrangement of n pseudolines in the real projective plane and let p 3 (A) be the number of triangles of A. Grünbaum has proposed the following question. Are there infinitely many simple arrangements of straight lines with p 3 (A) = 1 3 n(n − 1)? In this paper we answer this question affirmatively.
متن کاملOn Left Regular Bands and Real Conic-line Arrangements
An arrangement of curves in the real plane divides it into a collection of faces. Already in the case of line arrangements, this collection can be given a structure of a left regular band and one can ask whether the same is possible for other arrangements. In this paper, we try to answer this question for the simplest generalization of line arrangements, that is, conic–line arrangements. Invest...
متن کاملLine Arrangements in H
If M = H3/G is a hyperbolic manifold and γ ⊂ M is a simple closed geodesic, then γ lifts to a collection of lines in H3 acted upon by G. In this paper we show that such a collection of lines cannot contain a particular type of subset (called a bad triple) unless G has orientation-reversing elements. This fact allows us to extend certain lower bounds on hyperbolic volume to the non-orientable case.
