Invitation

Dear Knot at Lunch People,

We will have our next summer lunch on Thursday August 16, 2007, at the usual place, Bahen 6180, at 12 noon.

As always, please bring brown-bag lunch and fresh ideas. I'm not yet sure what the agenda will be - perhaps we will continue with the topic from our last meeting, or perhaps it will be something else.

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

We talked about $\sum _{k=1}^{n}k^{3}=\left(\sum _{k=1}^{n}k\right)^{2}$, about decompositions of polytopes, and about the $gl(N)$ Lie-bialgebra weight system.
