My session was about the talk "Meta-Groups, Meta-Bicrossed-Products,
and the Alexander Polynomial" I gave in Regina a week before. We
watched the video from that talk and interupted it a number of times
for comments, and at the end had a lengthy discussion with many more
comments. See the talk
page and handout and especially the talk
video.

Clip 1: Clarifying the local structure of w-knotted objects, the twist
relation, excellence conditions on associators, which is what in the
relationship between u→w, KV, AT, and AET.

Clip 2: The w-side equations (R4, unitarity, disk-unzip), jacobians,
proof of the equivalence with the AT version of the KV equations.
My June 13
Clip 1: The local structure of vertices, three formulations of the
u→w maps, the beta relations, "wheeling" in the w-world.

Clip 2: beta-calculus: the four basic operations, an evaluation example
with the virtual trefoil, the origin of the terms in the swap formula.

applications, the scheme of the Euler computation of Alexander.
