Algebraic Geometry Working Seminar

"Tropical Curves and Where to Find Them"

This talk will have three simple goals, first, what is a tropical curve/variety, second, how do we define them abstractly, and third, one tiny application. We will first define what a tropical semiring is, along with interesting applications of general theory of tropical geometry. Then we will specialize to tropical curves, talk about dual graphs, and the moduli space of tropical curves. Finally we will introduce one simple application of this to the cohomology of M_{g,n}.

This seminar will be held jointly online and in person:
