Content

The aim of this reading group is to understand the connection between Feynman integrals and amplitudes on one side and algebraic geometry, tropical geometry and D-modules on the other. These connections have appeared recently in different fields, such as enumerative geometry of real and complex curves, topology of moduli spaces of curves or numerical evaluations of Feynman integrals.
