Title: Stabbing Pairwise Intersecting Disks by Four Points Speaker: Prof. Paz Carmi, Computer Science, Ben-Gurion University 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.
