Computing symbols for Feynman integrals [Virtual talk]

Description

I will briefly review some recent progress in computing symbols/coproducts of Feynman integrals, which evaluate to multiple polylogarithms  (MPL) or their elliptic generalizations (eMPL). I will present an algorithm for directly computing the total differential of Feynman integrals as one-fold integrals of MPL, which iteratively gives the symbol (up to period terms for eMPL case). I will then apply it to the computation of total differential of double D-gon integral in D dimensions.
