Invitation

Dear Knot at Lunch People,

We will have our next lunch on Thursday October 23, at the (new and hopefully temporary) usual place, the seminar room on the 10th floor of 215 Huron St., at 12 noon.

As always, please bring brown-bag lunch and fresh ideas. I'm hoping to make a little map-handout, roughly showing the logical relations between all those things I am confused about. If the map will be ready by Thursday, we may talk about it. If not, we'll have to find something else to talk about.

Further information about this Knot at Lunch meeting may be posted later at https://drorbn.net/drorbn?title=Knot_at_Lunch_on_October_23_2008.

As always, if you know anyone I should add to this mailing list or if you wish to be removed from this mailing list please let me know. To prevent junk accumulation in mailboxes, I will actively remove inactive people unless they request otherwise.

Best,

Dror.

The Gospel in Seven $Z$'s

	$Z:B\to {\mathcal {A}}^{h}$	Classifies braids! Detected by Lie algebras!
1	$Z:{\mathcal {K}}(\bigcirc )\to {\mathcal {A}}(\bigcirc )$	Related to metrized Lie algebras!	Related to Chern-Simons theory and configuration space integrals! Has GPV formulas!
2	$Z:{\mathcal {K}}^{TG}\to {\mathcal {A}}^{TG}$	Enables "Algebraic Knot Theory"! Finitely presented! Related to Drinfel'd associators!	No-go theorems in bounded degrees. Extremely challenging to compute. Leads to "internal quotients"! Still challenging to compute.
