Abstract In approval voting, individuals vote for all platforms that they find acceptable. In this situation it is natural to ask: When is agreement possible? What conditions guarantee that some fraction of the voters agree on even a single platform? Berg et al. found such conditions when voters are asked to make a decision on a single issue that can be represented on a linear spectrum. In particular, they showed that if two out of every three voters agree on a platform, there is a platform… 
Piercing Numbers in Circular Societies
. In the system of approval voting, individuals vote for all candidates they find acceptable. Many approval voting situations can be modeled geometrically, and thus geometric concepts such as the
Approval Voting in Circular Societies: Piercing Numbers and Agreement
This paper explores piercing numbers and agreement in the setting where preferences can be modeled by arcs on a circle -- i.e., in circular societies with fixed-length approval sets, and gives bounds on piercing and agreement.

Double-interval societies
Consider a society of voters, each of whom specify an approval set over a linear political spectrum. We examine double-interval societies, in which each person's approval set is represented by two
Voting in Agreeable Societies
Examples of situations where sets model preferences and develop extensions of classical theorems about convex sets that can be used in the analysis of voting in "agreeable" societies are given.

The Supreme Court of the United States has held that bizarrely shaped congressional districts threaten the equal voting rights of U.S. citizens. Attempting to quantify this bizarreness, myriad
