Evaluating Feynman Integrals Using D-modules and Tropical Geometry
Henrik J. Munch
Feynman integrals play a central role in the modern scattering amplitudes research program. Advancing our methods for evaluating Feynman integrals will, therefore, strengthen our a…
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…
Restrictions of Pfaffian Systems for Feynman Integrals
Vsevolod Chestnov, Saiei J. Matsubara-Heo, Henrik J. Munch +1
This work studies limits of Pfaffian systems, a class of first-order PDEs appearing in the Feynman integral calculus. Such limits appear naturally in the context of scattering ampl…
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…
