Differential Equations for Definition and Evaluation of Feynman Integrals

High Energy Physics - Theory 2016-09-06 v1

Abstract

It is shown that every Feynman integral can be interpreted as Green function of some linear differential operator with constant coefficients. This definition is equivalent to usual one but needs no regularization and application of RR-operation. It is argued that presented formalism is convenient for practical calculations of Feynman integrals.
