Equations and degeneration

Zoom meeting: https://unipd.zoom.us/j/5332063266
ABSTRACT: Linear subvarieties are a class of special subvarieties in the moduli space of differentials on Riemann surfaces, which are defined by linear equations among periods. After motivating the study of linear subvarieties, both from the viewpoint of algebraic geometry and dynamical systems, we discuss a framework to understand degenerations of families of differentials. The goal is to explain the statement “The boundary of a linear subvariety is linear

Monodromy and non-archimedean geometry

ABSTRACT: We will present an overview of recent results on mondoromy and Milnor fibers in relation with non-archimedean geometry and motivic integration.
