Marco Zambon, from KU Leuven, will speak in the geometry seminar on Tuesday 3rd November at 2pm. The talk will be in O8.08 on the 8th floor of NO. Please **note the unusual room** which we are using whilst the Salle de Profs is being renovated.

Marco’s title is “*Multisymplectic manifolds, homotopy moment maps, and conserved quantities*”; his abstract follows.

Multisymplectic structures are higher generalizations of symplectic structures, where forms of higher degree are considered. We introduce a notion of moment map for such structures, based on Stasheff’s notion of L-infinity algebra, and by relating it to equivariant cohomology we are able to produce examples. Even though moment maps are quite involved, they admit a simplecohomological description. Finally, we discuss some geometric implications of our moment maps (the existence of conserved quantities).

I hope to see you all there!

I would also like to ask you for suggestions for speakers for seminars in the following term. If you have anyone you would like to invite then please let me know.
