On lines avoiding unit balls in three dimensions
Let B be a set of n unit balls in R3 . We show that the combinatorial complexity of the space of lines in R3 that avoid all the balls of B is O(n3+ε ), for any ε > 0. This re...

Polygon Reconstruction from Line Cross-Sections
We study the following geometric probing problem: Reconstruct a planar polygon from its intersections with a collection of arbitrarily-oriented "cutting" lines. We propo...

"Catalan traffic" and integrals on the Grassmannian of lines
One proves that certain numbers occurring in a problem of paths enumeration, studied by Niederhausen in [7] (see also [10]), are top intersection numbers in the cohomology ring of...

Finding Independent Sets in Unions of Perfect Graphs
ABSTRACT. The maximum independent set problem (MAXIS) on general graphs is known to be NPhard to approximate within a factor of n1-, for any > 0. However, there are many "...
