Tropical Feynman integration in the physical region
Michael Borinsky, Henrik J. Munch, Felix Tellander
The software feyntrop for direct numerical evaluation of Feynman integrals is presented. We focus on the underlying combinatorics and polytopal geometries facilitating these method…
Flow Oriented Perturbation Theory
Alexandre Salas-Bernárdez, Michael Borinsky, Zeno Capatti +1
Flow Oriented Perturbation Theory (FOPT) is a novel approach to Feynman diagrams based on the coordinate (position) space description of Quantum Field Theories (QFT). FOPT offers i…
Weight 2 cohomology of graph complexes of cyclic operads and the handlebody group
Michael Borinsky, Benjamin Brück, Thomas Willwacher
We compute the weight 2 cohomology of the Feynman transforms of the cyclic (co)operads and , and the top weight cohomology of the Feynman transfor…
The -equivariant Euler characteristic of the moduli space of graphs
Michael Borinsky, Jos Vermaseren
We prove a formula for the -equivariant Euler characteristic of the moduli space of graphs . Moreover, we prove that the rational …
Tropical Feynman integration in the Minkowski regime
Michael Borinsky, Henrik J. Munch, Felix Tellander
We present a new computer program, , which uses the tropical geometric approach to evaluate Feynman integrals numerically. In order to apply this approach in the…
The Euler characteristic of the moduli space of graphs
Michael Borinsky, Karen Vogtmann
The moduli space of rank graphs, the outer automorphism group of the free group of rank and Kontsevich's Lie graph complex have the same rational cohomology. We show that t…
