Title: "Quantization of two types of multisymplectic manifolds"
Room: MC 107

Abstract: We will be interested in quantization in a setting where the algebraic structure on C(M) is given by an m-ary bracket {.,,.}:mC(M)C(M). Quantization in this context is the same as in the symplectic case, where we have a bracket of just two functions except that now we are interested in a correspondence {.,,.}[.,,.], between an m-ary bracket and a generalizeation of the commutator. In particular we will be interested in two situations where the m-ary bracket comes from an (m1)-plectic form defined on M (i.e. a closed non-degenerate m-form), Ω, for m1. The case m=1 is when Ω is symplectic. Let (M,ω) be a compact connected integral K\"ahler manifold of complex dimension n. In both of the cases that we will be looking into, the (m1)-plectic form Ω on (M,ω) is constructed from a K\"ahler form (or forms):

(I) m=2n, Ω=ωnn!

(II) M is, moreover, hyperk\"ahler, m=4, Ω=ω1ω1+ω2ω2+ω3ω3 where ω1,ω2,ω3 are the three K\"ahler forms on M given by the hyperk\"ahler structure.

It is well-known (and easy to prove) that a volume form on an oriented N-dimensional manifold is an (N1)-plectic form, and that the 4-form above is a 3-plectic form on a hyperk\"ahler manifold.

It is intuitively clear that in these two cases the classical multisymplectic system is essentially built from Hamiltonian system(s) and it should be possible to quantize (M,Ω) using the (Berezin-Toeplitz) quantization of (M,ω).
