Towards the fibers of the tropical Prym-Torelli morphism
Abstract. Curves and abelian varieties are the most studied classes of algebro-geometric objects. The Torelli morphism relates the two worlds. Since it is injective, this is a strong and valuable tool. Prym varieties generalize Jacobians: they are the natural abelian variety associated to an étale double cover of curves. The Prym-Torelli morphism, however, is never injective. In this talk I will take the perspective of tropical geometry, where curves become graphs and abelian varieties become symmetric bilinear forms. I present partial results on the structure of the fibers of the tropical Prym-Torelli morphis: (1) In joint work with Dmitry Zakharov, we have identified positive dimensional fibers. These phenomena are exhibited through a matroidal perspective. (2) In joint work with Thomas Saillez, we proved an analog of Donagi's theorem. It induces a discrete structure in the fibers.

Drawing algebraic curves in OSCAR
Abstract. I will talk about how to visualize real plane algebraic curves given as the zero set of a polynomial in two variables using Oscar.jl. I will highlight performance and exactness issues using real world examples.
