WebGrothendieck-Teichmuller group. Using a result of Drummond-Cole, we de-duce that the Grothendieck-Teichmuller group acts nontrivially on M0; +1, the operad of stable curves of genus zero. As a second application, we give an alternative proof that the framed little 2-disks operad is formal. 1. Introduction WebJan 14, 2015 · Mathematician who rebuilt algebraic geometry.
