On the Sylvester-Gallai and the orchard problem for pseudoline arrangements
Jürgen Bokowski, Piotr Pokora
We study a non-trivial extreme case of the orchard problem for pseudolines and we provide a complete classification of pseudoline arrangements having triple points and $9…
Dispersion for the wave equation inside strictly convex domains II: the general case
Oana Ivanovici, Richard Lascar, Gilles Lebeau +1
We consider the wave equation on a manifold of dimension with smooth strictly convex boundary , with Dirichlet boundary conditions. We con…
Combinatorial configurations, quasiline arrangements, and systems of curves on surfaces
Jürgen Bokowski, Jurij Kovič, Tomaž Pisanski +1
It is well known that not every combinatorial configuration admits a geometric realization with points and lines. Moreover, some of them do not even admit realizations with pseudol…
Quasi-configurations: building blocks for point-line configurations
Jürgen Bokowski, Vincent Pilaud
We study point-line incidence structures and their properties in the projective plane. Our motivation is the problem of the existence of configurations, still open for few…
On topological and geometric configurations
Jürgen Bokowski, Vincent Pilaud
An configuration is a set of points and lines such that each point lies on lines while each line contains points. The configuration is geometric, topologica…
Enumerating topological -configurations
Jürgen Bokowski, Vincent Pilaud
An -configuration is a set of points and lines in the projective plane such that their point-line incidence graph is -regular. The configuration is geometric, top…
