DESCRIPTION:Title: <a href="https://researchseminars.org/talk/RSVP/10/">A 
 new approach to multiple elliptic polylogarithms</a>\nby Nils Matthes (Uni
 versity of Oxford) as part of Rendez-vous on special values and periods\n\
 n\nAbstract\nMultiple polylogarithms may be viewed as the monodromy of a c
 ertain "universal" unipotent differential equation on the projective line 
 minus three points. This observation lies at the heart of their relation t
 o mixed Tate motives\, a point of view which brings powerful new tools to 
 bear on the study of these functions and its special values.\n\nThe goal o
 f this talk is to describe an analogous picture for a once-punctured ellip
 tic curve $E'$. In particular\, we obtain a new description of the unipote
 nt de Rham fundamental group of $E'$\, generalizing and improving on previ
 ous works of Levin-Racinet\, Brown-Levin\, Enriquez-Etingof\, and others. 
 Joint work in progress with Tiago J. Fonseca (Oxford).\n
