Invitation

Dear Knot at Lunch People,

We will have our next not lunch on Wednesday February 11, in my office (Bahen 6178) at 2PM.

Peter Lee will bring goodies, and I beg him to keep it modest - we don't want to get into an escalating goodies-quality-war! After goodies, Jana will tell us more about the Alexander polynomial for tangles, or, as always, we may talk about something else.

Further information about this Knot at Lunch meeting may be posted later at https://drorbn.net/drorbn?title=Knot_at_Lunch_on_February_11_2009.

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.

Some Content

Dror talked a bit about the Trotter formula in relation to basis conjugating automorphisms of $F_{n}$ (see BBS/KAL-090211-145208.jpg and 2009-02/Trotters...) and then Jana talked a bit about Alexander Half Densities and the Burau representation (see Washington09.pdf and BBS/Archibald-090211-155032.jpg).
