## ARC Colloquium/ACO Student Seminar: Peter Winkler – Dartmouth College

(Pizza will be served at 1pm in Skiles 005)

Title:

Pursuit on a Graph

Abstract:

Pursuit games---motivated historically by military tactics – are a natural for graphical settings, and take many forms.  We will present some recent results involving (among other things) drunks, Kakeya sets and a ketchup graph.''  Lastly, we describe what we think is the most important open problem in the field.
