====== A Classification of Stringent Hyperfields ======

===== Abstract for the Combinatorics Seminar 2017 February 13 =====

A hyperfield is called //stringent// if a ⊞ b is a singleton whenever a ≠ −b. Every doubly distributive hyperfield is stringent. I will present a classification of stringent hyperfields.
