TITLE: Tropical geometry and mechanism design

ABSTRACT: How to make sure people to achieve an outcome "better for all" when a) everyone acts in their personal interest only, and b) we do not know the exact "motives" of each person?Crudely, this is the central problem in mechanism design, a branch of economics. In this talk, I show how insights from tropical geometry can solve such problems. Joint work with Robert Crowell.
