Topology and Geometric Group Theory Seminar
I will talk about a recent project which involves
interpreting the E2 operad (of little disks) and its cousins in terms
of an extension of algebraic geometry (namely logarithmic geometry),
and I will explain the problem of "Drinfeld associators" through this
lens, where it has a surprisingly simple and canonical solution. I
will not assume any background on Drinfeld associators or on
logarithmic algebraic geometry.
