Flow-oriented perturbation theory
Michael Borinsky, Zeno Capatti, Eric Laenen +1
We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by str…
Taming a resurgent ultra-violet renormalon
Michael Borinsky, David Broadhurst
Perturbative expansions in quantum field theory diverge for at least two reasons: the number of Feynman diagrams increases dramatically with the loop number and the process of reno…
Recursive computation of Feynman periods
Michael Borinsky, Oliver Schnetz
Feynman periods are Feynman integrals that do not depend on external kinematics. Their computation, which is necessary for many applications of quantum field theory, is greatly fac…
Bayesian Integrals on Toric Varieties
Michael Borinsky, Anna-Laura Sattelberger, Bernd Sturmfels +1
We explore the positive geometry of statistical models in the setting of toric varieties. Our focus lies on models for discrete data that are parameterized in terms of Cox coordina…
Computing Euler characteristics using quantum field theory
Michael Borinsky, Karen Vogtmann
This paper explains how to use quantum field theory techniques to find formal power series that encode the virtual Euler characteristics of and related graph co…
Resonant resurgent asymptotics from quantum field theory
Michael Borinsky, David Broadhurst
We perform an all-order resurgence analysis of a quantum field theory renormalon that contributes to an anomalous dimension in six-dimensional scalar theory and is governed b…
