Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 24 septembre 2013 à 11h15-12h15 en B107, Emily Burgunder nous parlera de : Kontsevich graph complexes

Résumé : Kontsevich proved that the Lie homology of symplectic Hamiltonians can be encoded as the homology of a Hopf bialgebra of graph complex attached to the commutative world. In this talk we will see some generalisation of this theorem : commutative world being replaced by operad, symplectic by a classical group, and we can consider Lie homology or its lifting to Leibniz homology.
