Straight Line Arrangements in the Real Projective Plane
نویسندگان
چکیده
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.

Arrangements of double pseudolines
An arrangement of double pseudolines is a finite family of at least two homotopically trivial simple closed curves embedded in the real projective plane, with the property that any two meet exactly four times, at which points they meet transversely, and induce a cell structure on the real projective plane. In this talk I will show that any arrangement of double pseudolines is isomorphic to the ...
متن کاملOn Invariant Line Arrangements
We classify all arrangements of lines that are invariant under foliations of degree 4 of the real projective plane.
متن کاملBeam & Shell Models for Composite Straight or Curved Bridge Decks with Intermediate Diaphragms & Assessment of Design Specifications
In this research effort, the generalized warping and distortional problem of straight or horizontally curved composite beams of arbitrary cross section, loading and boundary conditions is presented. An inclined plane of curvature is considered. Additionally, the stiffness of diaphragmatic plates has been introduced in the formulation in order to compare with the case where rigid diaphragms are ...
متن کاملCrossing by lines all edges of a line arrangement
Let L be a family of n blue lines in the real projective plane. Suppose that R is a collection of m red lines, different from the blue lines, and it is known that every edge in the arrangement A(L) is crosses by a line in R. We show that m ≥ n−1 3.5 . Our result is more general and applies to pseudo-line arrangements A(L), and even weaker assumptions are required for R.
متن کاملΠ1-classification of Real Arrangements with up to Eight Lines
One of the open questions in the geometry of line arrangements is to what extent does the incidence lattice of an arrangement determine its fundamental group. Line arrangements of up to 6 lines were recently classified by K.M. Fan [Fa2], and it turns out that the incidence lattice of such arrangements determines the projective fundamental group. We use actions on the set of wiring diagrams, int...
