Description

We present a method for the high-precision numerical evaluation of transcendental functions appearing in Feynman integrals, based on a natural extension of known techniques for approximating transcendental numbers by rationals. The method easily achieves 100+ digits of precision, is systematically improvable and applies broadly to periods of elliptic curves and Calabi-Yau manifolds, as well as to more general iterated integrals. We also discuss prospects for extending this approach to the direct numerical evaluation of complete Feynman integrals.
