Dear Knot at Lunch People,

We will have our first spring lunch on Wednesday January 9, at the usual place, Bahen 6180, at 12 noon.

As always, please bring brown-bag lunch and fresh ideas. The agenda: we may talk a bit about Hutchings' work on step-by-step integration of weight systems (see Hutchings' Integration of singular braid invariants and graph cohomology, Transactions of the AMS 350 (1998), 1791-1809 and my aborted Finite Type Invariants by the Species), or we may talk about something else.

Further information about this meeting will/may appear at

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.
