Description
The infrared structure of scattering amplitudes offers a natural path to organize bases of Feynman integrals according to their divergence properties. In this talk, I will describe two complementary approaches to this organization: an analytic approach that builds upon the theory of Landau singularities in momentum space, and a geometric approach based on the parametric representation of the integral. Focusing on the class of locally finite integrals, I will explore the relationship between these two methods and discuss potential applications of the results.
