Hugh C. Morris Lecture: Francis Su

When does a majority exist? How does the geometry of the political spectrum influence the outcome? What does mathematics have to say about how people behave? When mathematical objects have a social interpretation, the associated results have social applications.  We will show how some classical mathematics about the geometry of sets and their intersections can be used to model people's preferences and understand voting in "agreeable" societies.  This talk also features research with undergraduates.
