Tropical KP Theory on Banana Curves
Simonetta Abenda, Türkü Özlüm Çelik, Claudia Fevola +1
The Kadomtsev-Petviashvili (KP) equation is the cornerstone of integrable systems, whose solutions reflect deep connections in algebraic geometry. Banana curves are reducible ratio…
Algebraic and Positive Geometry of the Universe: from Particles to Galaxies
Claudia Fevola, Anna-Laura Sattelberger
In recent years, the intersection of algebra, geometry, and combinatorics with particle physics and cosmology has led to significant advances. Central to this progress is the twofo…
Euler Discriminant of Complements of Hyperplanes
Claudia Fevola, Saiei-Jaeyeong Matsubara-Heo
The Euler discriminant of a family of very affine varieties is defined as the locus where the Euler characteristic drops. In this work, we study the Euler discriminant of families…
Algebraic Approaches to Cosmological Integrals
Claudia Fevola, Guilherme L. Pimentel, Anna-Laura Sattelberger +1
Cosmological correlators encode statistical properties of the initial conditions of our universe. Mathematically, they can often be written as Mellin integrals of a certain rationa…
Principal Landau Determinants
Claudia Fevola, Sebastian Mizera, Simon Telen
We reformulate the Landau analysis of Feynman integrals with the aim of advancing the state of the art in modern particle-physics computations. We contribute new algorithms for com…
Landau Singularities Revisited: Computational Algebraic Geometry for Feynman Integrals
Claudia Fevola, Sebastian Mizera, Simon Telen
We reformulate the analysis of singularities of Feynman integrals in a way that can be practically applied to perturbative computations in the Standard Model in dimensional regular…
