Genus zero modular operad and absolute Galois group

Noémie Combe, Max-Planck-Institut Leipzig, Germany RIMS Kyoto, botanic annex + Zoom · JP:16:30 · FR:08:30

This talk is concerned with one remarkable fruit of the interaction between the creation of the theory of quantum cohomology and its connections with one of central objects of number theory: the absolute Galois group of the field of algebraic numbers.
Equipping \(\bar M_{0,n+1}\) with an additional algebraic structure motivated from Quantum theory and Gravity we investigate implications concerning the Grothendieck-Teichmuller group.
