DESCRIPTION:In this seminar I will review some new developments in the the
ory of scattering amplitudes which allow us to simplify the calculation of
complicated multiloop Feynman integrals\, relevant for high precision ph
enomenology at particle colliders\, by using geometrical insights. I will
describe at an introductory level some properties of Feynman integrals and
how their analytic calculation can be performed in terms of special funct
ions defined as iterated integrals of rational functions on complex algebr
aic surfaces. I will also show how the\ngeometry of these underlying struc
tures is determined by the physics of the problem under study.\n\nhttps://
