A quasi-finite basis for multi-loop Feynman integrals
Andreas von Manteuffel, Erik Panzer, Robert M. Schabinger
We present a new method for the decomposition of multi-loop Euclidean Feynman integrals into quasi-finite Feynman integrals. These are defined in shifted dimensions with higher pow…
Renormalization, Hopf algebras and Mellin transforms
Erik Panzer
This article aims to give a short introduction into Hopf-algebraic aspects of renormalization, enjoying growing attention for more than a decade by now. As most available literatur…
Feynman integrals via hyperlogarithms
Erik Panzer
This talk summarizes recent developments in the evaluation of Feynman integrals using hyperlogarithms. We discuss extensions of the original method, new results that were obtained…
Algorithms for the symbolic integration of hyperlogarithms with applications to Feynman integrals
Erik Panzer
We provide algorithms for symbolic integration of hyperlogarithms multiplied by rational functions, which also include multiple polylogarithms when their arguments are rational fun…
On hyperlogarithms and Feynman integrals with divergences and many scales
Erik Panzer
It was observed that hyperlogarithms provide a tool to carry out Feynman integrals. So far, this method has been applied successfully to finite single-scale processes. However, it…
