University of Michigan
Tropical Geometry Seminar
Fall 2005
Thursdays 5:10-7:00, 3866 East Hall

Tropical Geometry is a technique for reducing algebro-geometric problems to problems of piecewise-linear geometry. These polyhedral problems, in turn, often lead to challenging combinatorics. One prominent example is Mikhalkin's work on Gromov-Witten invariants of toric varieties. The goal of this seminar is to learn the foundations of the theory of tropical varieties, concentrating on such examples as (tropical) linear spaces, Grassmannians, and plane curves.
