Toward multiple zeta values cycles

Posted in
Speaker: 
Ismaël Soudères
Affiliation: 
Duisburg-Essen/MPI

Location: 
MPIM Lecture Hall
Parent event: 
Number theory lunch seminar

We will review the setting of Bloch-Kriz cycle complex over the
projective line minus three points.
We will then show how to recover in this context the algebraic cycles
associated to the classical polylogarithms
using a pull-back by the multiplication on the affine line.

For a low weight example, we will explain how a twisted multiplication
map allows to build more general cycles.
We will conclude by showing how  a multiple zeta value arises from
the Gangl-Goncharov-Levin seesaw process.
