  • A manifold associated to a topological ▫$(n_k)$▫ configuration
    Bokowski, Jürgen ; Strausz, Ricardo
    In the study of topological ▫$(n_k)$▫ configurations in the projective plane we have ▫$n$▫ pseudo-lines and ▫$n$▫ points. Precisely ▫$k$▫ of these points are incident with each pseudo-line and, vice ... versa, precisely ▫$k$▫ pseudo-lines are incident with each point. We describe a non-orientable 2-manifold associated in a natural way to a topological ▫$(n_k)$▫ configuration in the projective plane. Apart from being interesting in its own right, this manifold defines an equivalence class within topological configurations. It can be used to distinguish topological ▫$(n_k)$▫ configurations.
