Straight 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 کاملThe Projective Invariants of Ordered Points on the Line
The space of n (ordered) points on the projective line, modulo automorphisms of the line, is one of the most important and classical examples of an invariant theory quotient, and is one of the first examples given in any course. Generators for the ring of invariants have been known since the end of the nineteenth century, but the question of the relations has remained surprisingly open, and it ...
متن کاملThe Relations among Invariants of Points on the Projective Line
Nous considérons l’anneau des invariants de n points ordonnés sur la droite projective. L’espace (P)//PGL2 est peut-être le premier exemple intéressant d’un quotient GIT. La construction dépend du choix des poids pour les n points. En 1894, Kempe [K] a introduit un ensemble de générateurs (au moins dans le cas où tous les poids sont constants egaux à 1). Ici, nous décrivons les rélations entre ...
متن کاملConjugation-free Groups, Lower Central Series and Line Arrangements
The quotients Gk/Gk+1 of the lower central series of a finitely presented group G are an important invariant of this group. In this work we investigate the ranks of these quotients in the case of a certain class of conjugation-free groups, which are groups generated by x1, . . . , xn and having only cyclic relations: xitxit−1 · . . . · xi1 = xit−1 · . . . · xi1xit = · · · = xi1xit · . . . · xi2...
متن کاملArrangements 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 ...
