In this paper we investigate an approach for the numerical solution of differential equations which is based on the perfect discretization of actions. Such perfect discretizations show up at the fixed points of renormalization group transformations. This technique of integrating out the high momentum degrees of freedom with a path integral has been mainly… (More)
