Description
Analytic results for scattering amplitudes are generically expressed
in terms of polylogarithmic functions and their generalization. I review new mathematical developments that shed new light on the algebraic structure underlying these functions, and I show examples of loop integrals that,
using this framework, take an extremely simple and elegant form,
hinting towards a hidden simplicity in scattering amplitudes that waits
yet to be uncovered
