	* Infinitesimal Artin - derivations on free Lie algebras.
	** Derivations, tangential derivations, special derivations (see {{BBS Link\|Alekseev-080116-162451.jpg}}).
	** Drinfel'd's theorem on special derivations (see Drinfel'd's ''On quasitriangular Quasi-Hopf algebras and a group closely connected with <math>\operatorname{Gal}(\bar{{\Bbb Q}}/{\Bbb Q})</math>'', Leningrad Math. J. '''2''' (1991) 829-860, though I wouldn't be surprised if the theorem is actually older).
	** Can you prove that <math>{\mathcal A}^\mbox{hor}</math> injects into <math>{\mathcal A}^\mbox{trees}</math>?
	** The VS structure on several kinds of algebras of derivations. As always, can you find associators?
	** The Alekseev-Torossian "divergence" ({{BBS Link\|Alekseev-080121-093327.jpg}}).

Dear Knot at Lunch People,

We will have our next lunch on Wednesday February 13, 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 the infinitesimal side of Artin's theorem, or we may talk about something else.

Further information about this meeting will/may appear at <span class="plainlinks">{{SERVER}}/drorbn/index.php?title={{PAGENAMEE}}</span>.

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.
