Abstract

We prove that the filtration on the pure braid group on g strands, induced by the lower central series of the Torelli group of a genus g surface with one boundary component, coincides with its lower central series, shifted by one.

In particular, the cubic Jacobi relations in the pure braid group are quadratic relations in the Torelli group.
