FIG. 1: The covariance C φ , the Boulatov tetrahedral vertex T [φ], and the Freidel-Louapre pillow P [φ]
FIG. 3: The vertex operators. In the pillow case, the upper index labels the three different channels.
FIG. 5: The complete graph over 3 vertices, and its 7 forests, matching the 7 terms in (IV.5).
FIG. 6: Slicing the BFL vertices with an intermediate field σ over SU(2) 4 : the dashed lines are combined in the covariance C σ .
