* Title:  Integrable Systems in Symbolic, Numerical and Combinatorial
Algebraic Geometry*

*Abstract:* The Kadomtsev-Petviashvili (KP) equation is a universal
integrable system that describes nonlinear waves. It is known that
algebro-geometric approaches to the KP equation provide solutions coming
from a complex algebraic curve, in terms of the Riemann theta function
associated with the curve. Reviewing this relation, I will introduce an
algebraic object and discuss its algebraic and geometric features: the
so-called Dubrovin threefold of an algebraic curve, which parametrizes the
solutions. Mentioning the relation of this threefold with the classical
algebraic geometry problem, namely the Schottky problem, I will report a
procedure that is via the threefold and based on numerical algebraic
geometric tools, which can be used to deal with the Schottky problem from
the lens of computations. I will finally focus on the geometric behaviour
of the threefold when the underlying curve degenerates.

*Date: 26 March 2021*, Friday
