April Notices
Tuesday, April 10th, 2007The April Notices of the AMS features a retrospective on Serge Lang’s mathematical career. This month’s What is…, What is… a tropical curve. A tropical curve is a curve defined over the tropical semiring, which is the real numbers with addition defined as max or min, and multiplication defined as real addition. Mathematicians are currently working on finding the analogues of classical results on algebraic curves to the tropical setting.
