The so-called wonderful models of subspace arrangements, developed in [CP95] based on Fulton and MacPherson's seminal paper [FM94], serve as a systematic way to resolve the singularities of Feynman distributions and in this way allow to define canonical renormalization operators. In this thesis we continue the work of [BBK10] where wonderful models were(More)
Multiple polylogarithms are (locally) analytic, transcendental functions of several complex variables which generalize the logarithm Li 1 (z) = − log(1 − z) to They have many applications in mathematics but also in physics, where they occur frequently in computations of Feynman integrals. The algebra of rational linear combinations of such functions is in(More)
