GRT, MZVs and associators

Thursday, 20 August, 2015 to Saturday, 29 August, 2015

A. Alekseev, B. Enriquez, H. Furusho and S. Merkulov are organizing the workshop "GRT, MZVs and associators" on August 20-29 in Les Diablerets. The purpose of this workshop is to bring together the leading experts in the field of multiple zeta-values, associators and the Grothendieck-Teichmueller group as well as a number of young researchers. Its aim is to advance on several important problems: the relation between the Kashiwara-Vergne (KV) and GRT Lie algebras, the topological interpretation of the divergence cocycle, the theory of elliptic MZVs.

The workshop is co-sponsored by the NCCR SwissMAP, the grant "Algebra, Analysis, Geometry and Physics " of the Swiss National Science Foundation (SNSF) and the project MODFLAT of the European Research Council (ERC).
