We provide algorithms for symbolic integration of hyperlogarithms multiplied by rational functions, which also include multiple polylogarithms when their arguments are rational functions. These algorithms are implemented in Maple and we discuss in particular their application to the computation of Feynman integrals.
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)
