The motivic Lie algebra embeds into the cohomology of the general linear group

Francis Brown, Erik Panzer, Jean-Luc Portner

We show that the motivic Lie algebra of mixed Tate motives over embeds canonically into the unstable compactly-supported cohomology of locally symmetric spaces for $\m…

Unstable cohomology of and the odd commutative graph complex

Francis Brown, Simone Hu, Erik Panzer

We study a closed differential form on the symmetric space of positive definite matrices, which is defined using the Pfaffian and is invariant up to…

Positive geometries and canonical forms via mixed Hodge theory

Francis Brown, Clément Dupont

''Positive geometries'' are a class of semi-algebraic domains which admit a unique ''canonical form'': a logarithmic form whose residues match the boundary structure of the domain.…

Single-valued periods of meromorphic modular forms and a motivic interpretation of the Gross-Zagier conjecture

Francis Brown, Tiago J. Fonseca

A well-known conjecture of Gross and Zagier states that the values of the higher automorphic Green's function at pairs of points with complex multiplication in the upper half-plane…

Bordifications of the moduli spaces of tropical curves and abelian varieties, and unstable cohomology of and

Francis Brown

We construct bordifications of the moduli spaces of tropical curves and of tropical abelian varieties, and show that the tropical Torelli map extends to their bordifications. We pr…

The wheel classes in the locally finite homology of , canonical integrals and zeta values

Francis Brown, Oliver Schnetz

We compute the canonical integrals associated to wheel graphs, and prove that they are proportional to odd zeta values. From this we deduce that wheel classes define explicit non-z…
