abstract = {An automated treatment of iterated integrals based on letters induced by real-valued
quadratic forms and KummerPoincaré letters is presented. These quantities emerge in
analytic single and multiscale Feynman diagram calculations. To compactify representations, one wishes to apply general properties of these quantities in computer-algebraic
implementations. We provide the reduction to basis representations, expansions, analytic
continuation and numerical evaluation of these quantities.},
