Tropicalization of Theta Characteristics

David Jensen (University of Kentucky)

We will discuss recent joint work with Yoav Len on the behavior of theta characteristics in degenerating families of algebraic curves. Motivated by the concrete example of bitangents to a plane quartic, we will discover connections between graph theory, covering spaces, and quadratic forms.
