A topological inclusion from double shuffle Lie algebra to Kashiwara-Vergne Lie algebra.
31 mars 2026 - 14:00Salle de séminaires IRMA
Double shuffle and regularization relations is a distinguished set of relations among multiple zeta values. Consider those relations formally, G. Racinet introduced the double shuffle Lie algebra (dmr). The Kashiwara-Vergne Lie algebra (krv) was introduced by A. Alekseev and C. Torossian when they reproved the Kashiwara-Vergne conjecture using Drinfeld associators. In this talk, I will present a topological characterization of the skew symmetric part of dmr and symmetric krv. As an application, we prove the inclusion of skew-symmetric part of dmr with IHX relations to symmetric krv. It is based on the preprints: 2509.20275, arXiv:2601.19455 with collaborators and some ongoing work. -
