Abstract

When does a candidate have the approval of a majority? How does the geometry of the political spectrum influence the outcome? When mathematical objects have a social interpretation, the associated results have social applications. We will show how generalizations of Helly's Theorem can be used to understand voting in "agreeable" societies. This talk also features research with undergraduates.
