I will survey results related to coloring geometric hypergraphs that arise from range spaces. We will be interested only in the big/fat hyperedges, i.e., in the ones that contain many vertices. For example, recently we have shown (joint work with Damasdi) that any finite set of planar points can be 3-colored such that any unit disk containing at least 666 points contains two differently colored points, but the same does not hold for disks of arbitrary radius. In my talk I'll highlight some questions left open, for a complete list, see https:// | I will survey results related to coloring geometric hypergraphs that arise from range spaces.

We give a sketch of the proof that the maximum chromatic number of a circle graph with clique number at most $\omega$ is equal to $\Theta ( \omega \log \omega)$. | We give a sketch of the proof that the maximum chromatic number of a circle graph with clique number at most $\omega$ is equal to $\Theta ( \omega \log \omega)$. | ||
