Center node: "stabbing pairwise intersecting disks by four points"
  Abstract: Following the seminal works of Danzer (1956, 1986) and Stach\'{o} (1965,1981), and the recent result of Har-Peled et. al. (2018), we study the problem of stabbing disks by points. We prove that any set of pairwise intersecting disks in the plane can be stabbed by four points. Our proof is constructive and yields a linear-time algorithm for finding the points.
