*Titre:
« **On
linearized and elliptic versions of the Kashiwara-Vergne Lie algebra
**»*

Résumé : Using the theory of moulds developed by Ecalle, I will define the linearized and elliptic versions of the Kashiwara Vergne Lie algebra (originally constructed by Alekseev and Torossian). I will then describe the conjecture linked to the linearized version, and explore the ties of the elliptic version with earlier elliptic constructions of the double shuffle Lie algebra and the Grothendieck-Teichmüller Lie algebra.

This is joint work with Leila Schneps.
