Abstract
In this paper we show how results on the behaviour of analytically reg ularized Green functions which traditionally required detailed inspect ion of general Feynman diagrams, can be obtained straightforwardly, wh en combining this regularization with flow equations. In particular we prove the existence of the analytic minimal subtraction scheme. For s implicity we restrict to massive Euclidean phi4(4).
