SPEAKER: Ken Stephenson

TITLE: Yes, I am still doing circle packing!

ABSTRACT: Circle packings are configurations of circles with specified patterns of tangency. In this talk I will review the fundamentals of the topic by creating, manipulating, and displaying examples concretely using my software, CirclePack. This is appropriate for the analysis seminar because packings are a basis for discrete analytic function theory. Moreover, my talk will lay some of the background for a

subsequent talk by visitor Frank Martin.
