Dasha Poliakova (University of Copenhaguen) : « From polyhedra to operads. »
Résumé :
I will construct associahedra and multiplihedra – polytopes which are responsible for non-associativity in algebra. I will therefore introduce operads in general and A-infinity operad in particular. If time permits, I will discuss some contractions of associahedra and multiplihedra.
