Stable cohomology of graph complexes

Matteo Felder, Florian Naef, Thomas Willwacher

We study three graph complexes related to the higher genus Grothendieck-Teichmüller Lie algebra and diffeomorphism groups of manifolds. We show how the cohomology of these graph co…

Graph Complexes and higher genus Grothendieck-Teichmüller Lie algebras

Matteo Felder

We give a presentation in terms of generators and relations of the cohomology in degree zero of the Campos-Willwacher graph complexes associated to compact orientable surfaces of g…

On a homotopy version of the Duflo isomorphism

Matteo Felder

For a finite dimensional Lie algebra , the Duflo map defines an isomorphism of -modules. On -inva…

Filtrations on graph complexes and the Grothendieck-Teichmüller Lie algebra in depth two

Matteo Felder

We establish an isomorphism between the Grothendieck-Teichmüller Lie algebra in depth two modulo higher depth and the cohomology of the two-loop part of the grap…

Internally connected graphs and the Kashiwara-Vergne Lie algebra

Matteo Felder

It is conjectured that the Kashiwara-Vergne Lie algebra is isomorphic to the direct sum of the Grothendieck-Teichmüller Lie algebra …

On the irrationality of certain coefficients of the Alekseev-Torossian associator

Matteo Felder

We give explicit formulas for the first few coefficients of the Alekseev-Torossian associator and a second Drinfeld associator. This is done by analyzing the free and transitive ac…
