SubTropica
Mathieu Giroux, Sebastian Mizera, Giulio Salvatori
We present SubTropica, a Mathematica package that performs symbolic integration of multi-polylogarithmic integrals using recent advances in tropical geometry. It focuses on the cla…
SOFIA: Singularities of Feynman Integrals Automatized
Miguel Correia, Mathieu Giroux, Sebastian Mizera
We introduce SOFIA, a Mathematica package that automatizes the computation of singularities of Feynman integrals, based on new theoretical understanding of their analytic structure…
Records from the S-Matrix Marathon: Asymptotic Observables
Simon Caron-Huot, Mathieu Giroux, Holmfridur S. Hannesdottir +2
These lectures introduce the notion of asymptotic observables, which are classes of measurable quantities predicted by quantum field theory. In gapped theories with trivial infrare…
Records from the S-Matrix Marathon: Gravitational Physics from Scattering Amplitudes
Miguel Correia, Holmfridur S. Hannesdottir, Giulia Isabella +5
These lecture notes explain how classical gravitational physics emerges from scattering amplitudes. We emphasize the role of different kinematic regimes in probing various aspects…
Records from the S-Matrix Marathon: Tasty Bits of Several Complex Variables
Sean N. Curry, JiÅÃ Lebl, Mathieu Giroux +3
We will cover the basics of several complex variables in 4 lectures: Basic properties of holomorphic functions in several variables, the notion of pseudoconvexity, CR functions and…
