title = "Coloring curves that cross a fixed curve",

abstract = "We prove that for every integer t ≧ 1, the class of intersection graphs of curves in the plane each of which crosses a fixed curve in at least one and at most t points is χ-bounded. This is essentially the strongest χ-boundedness result one can get for this kind of graph classes. As a corollary, we prove that for any fixed integers k ≧ 2 and t ≧ 1, every k-quasi-planar topological graph on n vertices with any two edges crossing at most t times has O(n log n) edges.",
