Graphical Hyperlogarithms

Explore a groundbreaking lecture on graphical hyperlogarithms presented by Oliver Schnetz at the Hausdorff Center for Mathematics. Delve into a new class of hyperlogs that generalizes iterated integrals and is closely related to F. Brown's cell zeta values. Discover the graphical representation of these hyperlogs and learn about the coaction formula expressed in terms of subquotient graphs. Understand how the space of graphical hyperlogs remains closed under coaction. Gain insights from this 68-minute talk, which was part of the Hausdorff Trimester Program focusing on Periods in Number Theory, Algebraic Geometry, and Physics.
