Integration-by-Parts: A Survey,We present an overview of the field of Integration-By-Parts with special emphasis on Laporta’s algorithm. We give an overview of the problems associated with Laporta’s algorithm and try to illustrate possible ways out.

We first summarize the lessons learned from the study of the remainder functions of the 2 → 4 and the 2 → 5 scattering amplitudes and then present new results for the 2 → 6 amplitude.

Calculating Four-Loop Corrections in QCD,rs, with specific focus on deep-inelastic scattering and electron-positron annihilation. The calculations build on the parametric reduction of loop and phase space integrals up to four-loop order using computer algebra programs such as ., designed for large scale computations.

Expansion by Regions: An Overview,en limit where some kinematic invariants and/or masses have certain scaling measured in powers of a given small parameter. Prescriptions of this strategy are formulated in a simple geometrical language and are illustrated through simple examples.
