Closed-form analytic solutions for dilogarithmic double integrals. (English) Zbl 1118.81508

Summary: This note presents techniques for analytically solving double integrals of the dilogarithmic type which are of great importance in the perturbative treatment of quantum field theory. In our approach, divergent integrals can be calculated similarly to their convergent counterparts after identifying and isolating their singular parts.
