Speaker: Valeriu Soltan, George Mason University
Date and time: Thursday, January 31, 4–5pm
Place: Rome 352

Abstract: We discuss the following new result of combinatorial geometry: a disjoint family of six or more unit circular disks in the plane has a common support line provided every its subfamily of three disks has a common support line.
