Abstract: Taking our motivation from the Chern-Simons-Witten expectations for the asymptotics of the Reshetikhin-Turaev invariants, we will state (in very simple terms) an infant conjecture about some well-behaved measure-valued invariant of embedded trivalent graphs. We will explain how our conjecture could be relevant for the realization of the Chern-Simons-Witten expectations, and how our conjecture can be reduced to the existence of a special invariant measure on some three copies of any given compact Lie group. Finally we will show that in some perturbative sense, our conjecture is true and in fact equivalent to Drinfel'd's theory of associators.
